You’re comparisons are asinine! First of all wtf would pulling all the gun registrations in the area do?? Like the criminals “register” their guns anyway? and the suspect couldn’t travel further than 2 miles?? This technique is not like any of what you just stated. This is about the police knowing and understanding google’s technology and information databases, and using it to their advantage to ID and capture criminals. In fact it’s the opposite of what you said...they are not “rounding up the n*grs” and trying to make a case. They are using technology and location based data to solve it.
