HOW does the OP know this? Has the guy gotten mail there? Hence my question. I have heard a great many people make similar claims over the decades without any real proof other than paranoia or rumor. And, even if the bad guy had done this, it seems he has addressed it by changing the address ... which, I didn't know one could do on someone not you. But, I've never tried it.
And, note that the DMV is but one source for an address to be used on a search warrant. I know that I have never relied solely on one source for an address when used in a search warrant, and certainly wouldn't use it as the lone source when seeking dynamic entry. Understand that MOST search warrants are low-key affairs and no not involve surrounding a home with cars with flashing lights. Most arrest warrants are handled the same. In fact, most arrest warrants do not GET a home visit, they only get served if the bad guy is contacted out and about or in the course of normal patrol or other routine activity. There are too many warrants out there for law enforcement agencies to expend their limited resources on serving arrest warrants. There are hundreds of thousands of arrest warrants in CA, unless this guy is wanted for attempted murder or something, the police are not going to be hunting him down in any dramatic fashion.
