Damn, I don't think this scorpion fella is getting it. Typical to fixate so much on one small piece that the rest is lost.
"why put the store owner in danger"
Clearly the whole argument for this (by people that actually live in these parts) is to get these stores to go, thus the owner not being in danger as he has no business to run. If not, then comply and be treated as a sit in like the rest, thus not being in anymore danger than others (as you said, most restaurants don't have bullet proof glass in those parts).
That's usually how these threads go though. Clearly all of that was left out by some of these warroomers and all thats left is "THEY WANT TO TAKE AWAY BULLET PROOF GLASS IN THE GHETTO, HERP DERP".
