Yes. Good thinking. Maybe the victims could stand their ground, do not leave, sooner or later the restaurant will ask them to leave, both customers and mob. By that time, police may attend and, at least, photos taken.

The main line of attack has to be chopping government expenditure, even on good stuff, especially education.
We are told spending (other people's money) on education is an investment. Turns out, it creates a class of rent seekers, parasites, who threaten productive people.

They should be enforcing laws against harassment, regardless of motivation, simply because harassment infringes on people's rights. Doing so, unfortunately, will not make people use reason.

As far as the border issue, since the left doesn't want the invaders shot (like we did in Vietnam when they tried to invade our perimeter), I propose we hand them a flyer and wish them the best. Perhaps even provide bus service to drop them off at their destination. The flyer should specify all the names and addresses of all those that created this issue, with instructions on how to get there and what to expect. It should specify the size of the wonderful yard around the mansions, and tell them that it will be a secure area for their families inside a fenced or walled in area with security guards also for their protection. And if they knock on the doors someone will provide them with food and clothing and perhaps even a little spending money to get them started on a productive life. Then we can see how Pelosi, Waters, Pocahontas, Obama, Schumer and even the mainstream media "stars" actually think about and handle the situation. Reality just might set in, give them exactly what they want.
