Twitter has suspended the account of @Instapundit, a.k.a. Glenn Reynolds, for recommending that people trapped by rioters use their cars to escape and protect their own lives. Here's the offending tweet:
Perhaps Professor Reynolds should have written "keep driving", or something less intemperate. Of course it would be illegal and immoral to use deadly force against a peaceful protester, but the protests in Charlotte have been quite violent.
It's both lawful and moral to use deadly force to protect your life and property.
