Hello. My boyfriend recently went to jail due to a warrant for assault on a family member-strangulation but he 1) paid to have his warrants taken off.

A traffic stop must be legal, or any of the evidence discovered after the stop can be suppressed as the fruit of an illegal search / seizure. He should hire an attorney on the assault family violence -impeding breath (strangulation) case. District Attorney offices prosecute these aggressively and just because the victim is a drug addict or in jail does not mean they will dismiss his case. Many of these types of cases end up getting set for trial. Your boyfriend should make sure he trust his attorney to defend these type of serious charges.
