Of course they weren't, someone was just shot and it was a mega what the fuck moment for everyone who was focused on the poor girl..........
Now this type of occurrence may be common for you and wouldn't faze you in the least, and for that I salute and admire you, but for these people, it was definitely a once in a lifetime shit hits the fan moment..........
I didn’t say they should be unfazed my point was the group wasn’t a violent threat and the arriving officers saw that immediately.
