Can cops search your sons computer?

Answer 1

Yes, with a warrant the police can check the contents of your computer, as well as the contents of your sock drawer, the trunk of your car, and anything else that is named in the warrant. They can also confiscate the computer (or your sock drawer, or your car) to do this.

If you are doing something illegal on your computer, deleting the files will not save you. The delete command simply places a note in the system registry to make that space available if needed. If it is never needed, the file will remain forever and can be retrieved by a person knowledgeable in computer forensics.

So, whatever it is you are doing (counterfeiting, child porn, hate messages, hacking, viruses) stop doing it or you will have to burn your hard drive every time you feel that twinge of paranoia.

One day there will be a knock at your door.

Answer 2

That's a pretty broad question but - yes. With his permission. With the proper warrant or, under "exigent circumstances," without one.
