1, evidence collection must be active and timely. If you call 1 10 in case of a criminal case, the police will call the police immediately. The more timely the report, the more timely the evidence collection. In judicial practice, the delay in evidence collection is mostly due to the delay in reporting the case by the parties.

2. Collecting evidence should be purposeful and planned. In a murder case, we should first investigate the person who has a grudge against the owner, and gradually narrow the scope of suspects through investigation to determine the key suspects.

3. Collect evidence objectively and comprehensively. Objectivity means opposing preconceptions and subjective assumptions. Comprehensive, that is, it is necessary to collect evidence to prove that the suspect is guilty and to collect evidence to prove that the suspect is innocent.

It is very important that the subject of evidence collection and provision must have legitimacy. At present, the main body of collecting and providing evidence is the staff of public security and judicial organs, the parties and their agents ad litem. Secondly, the method of obtaining evidence must be legal. In order to ensure that the collected evidence is legal and valid, the law prohibits the collection of evidence by illegal and improper methods. And the evidence collected by illegal means cannot be used as the basis for finalizing the case.

To collect evidence in depth and in detail, in-depth investigation and evidence collection is often different from the superficial phenomenon.

Rely on the masses and combine scientific and technological means, because any crime will leave traces. Find more people to investigate, and the more clues you can collect, the more comprehensive you will be. Instead of telling the masses that they are suspected without trial, inciting people who don't know the truth to shout slogans and suppressing justice with public opinion. With the continuous development of science and technology, we should make full use of advanced scientific and technological means to obtain evidence and identify its authenticity.

We must strictly abide by legal procedures, pay attention to keeping secrets, and strictly prohibit extorting confessions by torture and collecting evidence by threats, enticements, deception or other illegal methods.

Evidence must be fixed in time and properly preserved. If the original evidence cannot be preserved or attached for a long time, it should be photographed and copied in time, and detailed records should be made.
