I like that idea. It could catch on.
It would kind of be like Leftist's "swatting" conservatives, only it would have the added appeal of highlighting the fact that Muzzies are a never-ending source of real-life suspicion. Their neighbors would mistrust them ever-after. And it would send the Left into apoplexy.
As long as it could be done with the cover of legitimacy - as in, you actually did spot a Muzzie doing something in public - the accusation of suspicion would be purely subjective. Kind of like a panty-waist calling the cops on an open-carrier because they felt "threatened' or "intimidated".
One could easily make the same claim upon seeing a Muzzie in a public place...
"I felt threatened and intimidated. They looked suspicious, like they were up to something. I thought I heard them say something about "al Qaeda" and... let's see... what was it again... something like, 'Allahu Akbar' maybe? No officer, I didn't actually see a weapon, but I couldn't tell for sure, so I thought I'd better call, what with Boston and all. One can never be too safe, and Big Sis says, 'if you see something, say something.' So here I am, doing my civic duty."
