SWAT'ing is trivially performed. Sign up for VoIP service, dial 911. Many systems also have normal phone numbers that go into a 911 center, or to a failover call processing place.
Police departments will also let you submit crime reports online. I "swatted" myself by accident after filing a report because one of my license plates was missing. I didn't get any follow up, so I figured I'd just go deal with it later. A bit after that, a cop pulls me over, draws his weapon, aims -- because my car pops up as stolen on his scanner. If someone was to file such a report on someone with concealed carry, I'll be the outcome could be pretty bad.
The owner of a supposed stolen vehicle having a concealed carry license shouldn't change the cop's attitude and behavior, and we're of course taught not to do stupid things in situations like this. Cops deal with legal concealed carriers all the time (> 8 million licences nation wide, some states don't require one), with a paucity of horror stories.
I had two plates, and I guess one fell off or got stolen or something. So I still had my back plate on. Since the PD never confirmed anything after the online report, I figured I would have to go down and do it in person some time. But apparently not.
Since there was zero confirmation, this means you can just do the same to anyone. If the person is particularly jumpy, disabled, has mental issues, etc. it could easily get serious.
