Okay, so: we ate more or less agreed on capture over any of the other options. Sounds like Lamar will probably have to be injured to be able to be brought in.

The jail could be used to at least stash Lamar temporarily? If he's as strong and fast as is suggested he'll probably need to be watched, and it sounds like the jail will have a steady flow of people around so even if not actively guarded he will have eyes on him at all time.

As to the interrogation, having someone to amp up his fear etc will make his mind easier to get into. Still painful for him, probably, but it's not going to be done with the active intent to torture. Depending upon the information gotten they could then decide what to do with him?
