Or is it whoever (edit: in the Wichita police) dispatched them without checking the details of the call, or adequately briefing them that the details were not clear?
Because the guy who shot made a huge and deadly mistake, but the fact that you can call 911 and have someone SWATted is a big problem on its own.
SWATing should just lead to a bit of wasted time, and a “sorry to bother you sir”. With proper response procedure it should be a complete non-issue. Placing blame on anyone but the cops is completely discounting the problem.
I am saying it should be placed on the cops' boss.
I agree with you that those should have been the consequences---i.e., none. Though, in a country where SWATting is a thing, whoever placed the call is very much responsible too, because he must have known the possible effect of his prank.
All in all, the cops (while responsible) don't have the largest slice of responsibility.
Police officers that shoot ppl should be held liable as well as the SWAT caller.
