These people are idiots who are going to get hurt. All it will take is for the criminals and thugs to get huge tractor trailers or big trucks to drive right through their barricades. What's their plan when the thugs show up with rifles, machine guns, and flame throwers? Not to mention they run the risk of the thugs burning down their homes, kidnapping them, and blowing up their cars. This isn't Hollywood and they will not win against the crime syndicate.
