Tear gas for self-defence

Big riots in Greece so out of control are rare but I've seen them happen in other countries too (US, France). My experience in Greece is that shop owners are completely defenseless, the Greek police cannot protect the streets or the shops. I remember when Bill Clinton visited Athens and the city was burnt down. He cut his trip short and went for a 'safe' trip in Turkey next door. As a better alternative to guns or hiring snipers from abroad, shop owners in Greece should arm themselves with tear gas and use it to protect their property. It takes 1 hothead shop owner to start shooting at protesters destroying his property or threatening his life. If caught he can claim self-defense.

But with no police around and fire and smoke all over no one will see him or his sniper firing. This is the scenario of all hell breaking loose with many dead people. If the police can't protect, tear gas is better self-defense to guns.
