Here's a drive through incident we recently had.
We have a large old two lane bridge west of Kansas City. The bridge leads from Leavenworth, KS to the Missouri side. Last week at 5pm a car stops in the middle of the bridge quickly backing up traffic. The driver gets out on the bridge, and starts shooting cars stopped striking a couple people.
A soldier from Ft. Leavenworth who's stopped on the bridge sees what's going on. He pulls out, quickly accelerates, and runs over the shooter as he shoots at the soldier and his vehicle. The soldier wasn't hit, the shooter is in critical condition. Hard to say how many lives were saved.
