This doesn't seem like an overreaction or anything.
A woman went into a deli in Philadelphia a few weeks ago and said she wanted to buy beer . . . but she didn't have any money. And the owner said no, you can't have free beer.
Which apparently made her so angry that she grabbed a can of hairspray and a lighter . . . and made an improvised FLAMETHROWER.
And then she used it to torch a bunch of items in the store while the owner ran away.
Fortunately the fire didn't spread . . . and the police are still trying to track down the woman.
