The business owners should have defended their own businesses. You can't rely on anyone but yourself. The government fucked up the one job that's clearly within their purview(defense against threats within and without). It should be a wakeup call for the big government fanboys.
They shouldn't have to. We're supposed to live in a civilized society, not the bloody wild west.
And it most certainly won't be a wake up call. In the eyes of the socialists, it only confirms their beliefs. They don't really care about those small business owners, because they lump them in the same camp as the big corporate thugs. Doesn't matter if their livelihood is ruined. Doesn't matter their employees are now out of work because the shop can't open. They're all the "man" and in some twisted way, they deserved it.
There's a culture of entitlement in these communities. If they want something, they take it. To hell with the repercussions, because society owes a debt to them. I want those cigars, I'm taking them, you owe me. I don't want to go to school, you owe me. Take care of my illegitimate children, you owe me. Pay me money for sitting on my ass all day, you owe me. The naive socialists eat this bullshit up like it's chocolate ice cream. At best they're enabling this behavior, at worst profiting off it. Everybody loses in the end.
It's not to say that policing in America doesn't have issues, and there aren't bad/trigger happy cops out there. It's a big issue that needs to be tacked. Especially in the post 9/11, post PATRIOT ACT world. However, taking your anger with the cops out on innocent people makes you the greater villain.
