If police start monitoring someone they break their annonimity and their unlinkability they have with their actions. What methods should they use to monitor the criminal without breaking their annonimity and unlinkability. –  user43564 Apr 7 at 10:07
    
Sorry but you are asking a question related to legal requirements which are different for every single country and sometimes even region. Also why would the police car about not breaking their privacy? –  Lucas Kauffman Apr 7 at 10:08
    
It's a project for my school , thats why I'm asking. Police would care because thats the law, which means police cant enter your house without a reason and take your hard drives. –  user43564 Apr 7 at 10:17
    
A common criticism of cyber policing is that the police regularly do invade user's privacy. While real world searches have legal protections, these are sometimes bypassed for cyber searches. –  paj28 Apr 7 at 11:07

The police in most (if not all) countries obeys to various investigation laws and clear legal frameworks that determine what they are authorized to do, how, when, etc.

Usually to wiretap a communication, a police officer has to obtain the approval of a judiciary authority (e.g. an independant judge).

There might be exceptions to those rules in case of specific investigations and/or when there is urgency to act (e.g. terrorism, or a crime that is going to be commited soon), but again those cases are well defined in the law to prevent abuse/mis-use by the authorities.

All the administrative procedures, paperwork, approvals, authorizations etc. have to be stricly followed in order for the evidence to be received by the court.
