What do you think a restraining order would do, and against whom?

Car chase & citizens arrest is where we can argue lines were crossed, sure.

But, the cops were not going to do a multi-night, multi-hour, multi-man surveillance operation to catch the guy in the act.

At the very least, the brothers needed to do this to collect evidence about who the guy was, and hand that over to the cops. Or contact him by phone/social media to let him know they know who he is and what he has been doing.
