I wouldn't want to try to rush the shooter, but I'm not a cop in body armor with a gun attached to a shield. That being said, can any word cover it other than 'cowardly'? I'd be open to other descriptors, but it seems like a horrific, shameful failure.

Now compare that to all the people who were privy to the plans to shoot up the Capitol on Jan 6. Inviting militias to overthrow the government should seem offensive to most real Americans. How much different is the cowardice of the various co-seditionists embedded in the FBI, the Pentagon, the DOJ, the Congress, the White House staff, and all the agencies monitoring social media that saw IN ADVANCE that Trump planned a coup using militias.
