I can think of a hundred different solutions. So yes using a service revolver to execute an unarmed belligerent, that's the easy way. Preferred...? Well it's hard to argue that wasn't his choice since it's the one he made. Unless of course you are gonna tell me that was the cop's only choice. But remember I don't believe in the no -win and I don't mind getting in a scrap. Just having the gun seems to reduce one's options. Hmm.. maybe that's why the British pulled service revolvers from standard issue.
But you're forgetting one thing Mike, Wilson had already been beat down once by Brown, there's no doubt that he wasn't capable of taking him on in hand to hand combat. Your, or I. Another matter entirely, but Wilson obviously was in no condition to fight at that point.
And for a LEO, it isn't about being willing to fight anyway, it's about stopping a criminal as quickly and safely as possible.
I'm not arguing that shooting him was the safest, quickest way to end things, I'm merely saying that we don't ask our cops to "be willing to get in a fight" , especially with a person who has already kicked their ass once.
Life isn't Walker Texas Ranger. Not every cop walkin around has a black belt and only carries a gun as a fashion statement.
