For those saying that he should have let him drive away and give chase, is that really wise?
Dude was obviously super drunk. Probably not a great idea to let him roam the streets at high speeds where he could have killed innocent people.
Would you have the same stance if the drunk guy sped away and killed a young family during the chase by crashing into them?
Sure the driver didn't have a gun, but a 4,000 lbs of speeding metal is a deadly weapon itself.
We can't truly assess the situation until the video is released.
