that was a threat, you're playing games. let a cop ask you "should I arrest you for talking out of line?" when you complain about some honkey doing some bullshit like aiming assault rifles at them (as they did at the Bundy Ranch standoff) and not getting arrested for it and I want you to keep that same demeanor. you trying too hard ol head.
It's not a threat, it's conditional. "If" makes it conditional. If I say I'm going to bust you in the head, it's a threat. If I say if you do xyz I will bust you in the head that's not considered a threat, per our local law enforcement. Terry didn't even go that far, he said "if you think". That's an common expression.
