Details are still scant, but…
“I mean, he had a lot of ammunition in that house, and certainly … all of us were strapped, you know, with ammunition, and we were calling for additional ammunition,” Kraus said. “Like I said, we tried to give him every opportunity to come out.”
…I’ll go way out on a limb and suggest that this could’ve been handled better.
Quick google search: Average rent in Pittsburgh: $1,531. Cost per bullet: $0.08 to $3 per shot depending on size. Number of bullets shot: Well, lets assume 30/minute, as that is what I found on google as the fastest you can shoot an non-automatic (I don’t know what kind of gun he used or if he was perpetually shooting, this is just for math). So the cost of doing 30 shot/minute for 6.5 hours would be from $936 to $35,100. More for semi-automatic, less for shooting less.
So… probably shot a month’s rent worth of bullets in those 6.5 hours. Others could get you closer, google isn’t what it use to be.
