Why is fingerprint analysis not accurate in crime?

Answers

Answer 1

Answer:

It is only accurate if the criminal is already in the police database.

Explanation:

The print is matched with a fingerprint that is already in the system.

Answer 2

No one disputes that fingerprinting is a valuable and generally reliable police tool, but despite more than a century of use, fingerprinting has never been scientifically validated. This is significant because of the criteria governing the admission of scientific evidence in the US courts. Latent fingerprints, which are collected from crime scenes, have been used as courtroom evidence for decades. ... But there is little certainty that a set of fingerprints can reliably point to the right person, according to the report.

Calcular trabajo realizado al transportar una carga de 3nc a un punto donde la carga de potencial es de 3E3

Answers

Responder:

9 * 10 ^ -6 julios

Explicación:

Dado que :

Carga, q = 3nC = 3 * 10 ^ -9 C

Diferencia de potencial, ΔV = 3E3 = 3 * 10 ^ 3 V

Usando la relación:

ΔV = trabajo realizado, con carga, q

Trabajo terminado, W = ΔV * q

Ancho = (3 * 10 ^ 3) * (3 * 10 ^ -9)

W = (3 * 3) * 10 ^ (3-9)

W = 9 * 10 ^ -6 julios

Trabajo terminado = 9 * 10 ^ -6 julios

7. What part of the economy finances public goods?
consumers
public sector
private sector
free riders

Answers

Answer: public sector

Explanation: Correct on Gradpoint

The part of the economy that finances public goods is the public sector. The correct option is B.

Public goods are products or services that are available to all members of society and that are neither exclusive nor competitive, meaning that one person's use of them does not affect how readily available they are to others.

Public goods must be provided and financed by the public sector, which is made up of several levels of government. To pay for the provision of public goods and services that benefit society as a whole, the government collects taxes and other income from people and businesses.

Thus, the ideal selection is option B.

Since the plantation owner enacted the laws and set the punishments, his opinions and disposition affect the handling of any crime committed and they could be lenient or harsh based on these factors.

How were the plantations of the old south administered?

The plantations of the old south were administered solely by the individual owners without any government intervention.

Every decision depended on the whims and caprices of the landowner.

Describe justice and its kinds.

Answers

Answer:

Justice is the principle of balancing or reconciling human relations in society in such a way as enables each one to get his due rights, towards and punishments. 8. Justice has several dimensions: Social Justice, Economic Justice, Political Justice and Legal Justice.

The three types of justice are distributive, procedural, and interactional.

I hope it's helpful!


Justice is action in accordance with the requirements of some law. Whether these rules are grounded in human consensus or societal norms, they are supposed to ensure that all members of society receive fair treatment. Issues of justice arise in several different spheres and play a significant role in causing, perpetuating, and addressing conflict. Just institutions tend to instill a sense of stability, well-being, and satisfaction among society members, while perceived injustices can lead to dissatisfaction, rebellion, or revolution. Each of the different spheres expresses the principles of justice and fairness in its own way, resulting in different types and concepts of justice: distributive, procedural, retributive, and restorative. These types of justice have important implications for socio-economic, political, civil, and criminal justice at both the national and international level.

Which of the following is true regarding a guilty plea in a criminal case?
O It operates as an admission of the charge only, not the underlying facts
O It may be the basis for establishing facts in a later civil case
O It will occur as a part of the trial portion of a criminal prosecution
O It is legally equivalent to a “no contest” plea

Answers

The one that is true regarding a guilty plea in a criminal case is option A. It operates as an admission of the charge only, not the underlying facts. Hence, the correct answer is option A

A criminal case is the one that is liable to sentence punishment. A case that is punishable under law of any country. Hence, one is set to be in a criminal case when one is involved in any form of crime. The severity of the crime determines the gravity of the punishment.

What does guilty plea mean?

To plead guilty implies that one accepts that one did the crime charged. If one pleads guilty, the court will decide what should happen next, which could be a fine or a prison sentence.

Therefore, the correct answer is option A. It operates as an admission of the charge only, not the underlying facts.

Introduction: The people of Switzerland were being ruled by the Emperor of Germany who desired to break their independent spirit. This Emperor appointed a cruel, unjust man named Gessler to be governor over the Swiss people. The Swiss people were afraid of the evil governor all except for William Tell. Setting: A crowded marketplace in the middle of town. Scene IGessler's messenger: ( yelling as he drives a pole into the ground) Here Ye, here ye people of Switzerland! The honorable Gessler desires a show of respect. ( he places a hat on the top of the pole) Gessler's messenger: All who pass this way must bow down before this pole and cap to show their allegiance to our great and powerful Emperor of Germany. ( the towns people gasp and murmur in disbelief) Peasant man 1: What is this? I will not do this thing you ask. Gessler's messenger: ( striking the peasant man) You will do as you're told! Peasant man 2: What is the punishment for disobeying this ridiculous request? ( enter Governor Gessler) Gessler: I will answer this. To any person who disobeys my orders he will be given a sound beating and a damp, diseaseridden jail cell to sleep in! ( sounds of crying and gasping from the crowd) Townspeople: No, please, say it isn't so! ( The crowd begins to disperse; mothers grab their children and run to their houses.) Gessler: ( shouts) I will be watching. ( Gessler exits) Scene II( A few days later, William Tell and his son John enter the marketplace.) John: ( pointing to the pole) Father, why does everyone bow low as they pass that pole and cap? William: ( grabbing John's arm) This looks like the evil Gessler's doing. Wait here and I will find out who is attempting to put this town in chains! William: ( speaking in a concerned voice) Friends, what is going on here? Why do you bow to this stick? Peasant man 1: We have been commanded by the mighty Gessler to do so! Peasant man 2: Not bowing is a crime punishable by beating and possibly death! William: ( speaking loudly to the crowd) I will not bow! I will not become a slave to the tyrant king of Germany! ( Gessler enters quietly behind William) Gessler: ( pointing his finger angrily at William) Then you will answer to me! ( Gessler walks toward William and stands before him.) Scene III( enter Gessler into the marketplace a few hours later, with William in chains) Gessler: People of Switzerland, here is an example of foolish bravery. Because this William Tell did not follow orders and proceeded to excite the townspeople against the honorable King of Germany, his punishment is death! Townspeople: oh no, not William! This is terrible! Have mercy! Gessler: ( smiling) You want mercy, alright! I'll give you mercy. I will spare his life on one condition: William must shoot this apple off the top of his only son's head!! ( Gessler throws a bow and some arrows at the feet of William) John: ( calmly looking at his father and speaking quietly) Do what you must do. You are a clever archer, the best I've ever known. ( John is placed 20 yards away from where his father stands. The target is placed on his head.) William: ( glaring at Gessler) This is a horrible proposal and one I will not soon forget. If I succeed, I will hold you to your word and expect my freedom. Gessler ( looking across the way at the boy) If you succeed, you will have it. ( William picks up two arrows and places one in his shirt. With the other he takes aim. The crowd watches as the arrow flies, hitting its mark perfectly.) Townspeople: Hurray! What amazement! Young John is saved and so is our Brave William Tell! Gessler: ( enraged the boy was not hit) You lucky fool! Next time you will not be so fortunate!
