You're entitled to your opinion. But American history and the law are against you.
The Posse Comitatus Act is widely misunderstood by both the left and right. The author is basically wrong to write "prohibit[s] the use of the military in enforcing laws." It's semi-common for military forces to enforce laws or help enforce laws.
(For one thing, the Act only applies to the U.S. Army, not to National Guard or other troops working under state command. And even with regard to the U.S. Army there are exceptions in the law.)
I miss understood the law my mistake..
