Cops don't normally tell somebody to put their hands up, contrary to what TV says. If this guy had a weapon, or was reasonably believed to have one, and moved in the slightest way, he needed shooting.
That's ridiculous. If you can't determine whether or not he was armed at 20 ft, you need to be in the Helen Keller Institute.
Chinese throwing stars would have posed a bigger threat than a knife at that distance.
The scared or panic stricken don't need to wear a badge...or this happens.
They better pray he was holding a grenade or they're toast.
