Why is it difficult to use DNA as evidence in a crime before PCR was invented?
Before PCR was invented, it was difficult to use DNA as evidence in a crime because traditional methods required a large amount of DNA sample, which may not have been available or may have been contaminated. This made it challenging to obtain reliable DNA profiles for comparison. Additionally, the older techniques were more time-consuming and less sensitive than PCR, making the process of analyzing DNA evidence slower and less accurate.

Why was it difficult to use DNA as evidence in a crime before par was invented?
Before the polymerase chain reaction (PCR) was invented, it was difficult to use DNA as evidence in crimes because the available methods required relatively large quantities of DNA for testing, which were often not obtainable from crime scene samples. Additionally, existing techniques for analyzing DNA were time-consuming and less sensitive, making it challenging to obtain reliable results from degraded or contaminated samples. PCR revolutionized forensic science by allowing for the amplification of minute amounts of DNA, enabling more accurate and efficient analysis.
What part of the crime scene is the most difficult to preserve?
forensic evidence
Can you kill in international waters?
No. A crime at sea is still punishable under national and international laws. But when there is no report by witnesses, and little evidence of a crime, it is difficult to prosecute offenders.

How evidence can be destroyed at a crime scene?
It is illegal to destroy evidence at a crime and can result in jail time.
Do you need to be charged for a crime before police can take belongings for evidence?
No.Additional: If the police have probable cause to arrest you for the crime they can begin gathering and/or preserving evidence of the offense immediately without awaiting the formal court charging documents.
Why is it important not to contaminate a crime scene?
The answer is in your question: contamination. To contaminate something is to adulterate it, to ruin it. In this case, it is the evidence that is ruined. Contaminating a crime scene is essentially making a difficult job performed by an often less than qualified group of people far more difficult than it should be or needs to be. It seriously reduces the potential to secure a conviction of whomever committed the crime at that scene. That, and you could be criminally charged with a variety of misdemeanor and/or felony complaints.
What must be proven before the police may obtain a search warrant?
Before the police can obtain a search warrant, they must demonstrate probable cause to a judge. This means they must provide sufficient evidence to show that it is likely that a crime has been committed and that the search will uncover evidence related to that crime.
