I'll find it for you.. ask your local police or law enforcer. road blocks are one thing. But on a blind corner It's a "DeadMan's Blockade" tactic. especially with a shooter coming out from the woods. they knew right where to put them.  The FBI pulled a move to kill somebody. and that's what happened..  by the by.. they we're on their way to have a meeting with the sheriff.  not robbing a bank. big difference.
