You assume that the "supporters" for the most part are unchecked. In my experience "supporters" dont show up randomly and for the most part are orchestrated.
Bush was in Jacksonville last week the list of "supporters" was made in advance. How times did you see Monica in the front row of Clinton "supporters". You dont think she just happened to be there? These things are mostly staged.
You need to look into laws surrounding public assembly. They arent as clear as you try to portray. In some states "known gang members" cant congregate together. To stage marches or protests etc you need to abide by local ordinances.
The government has set rules on "free speech", it always has. But like the other guys here I wonder why its "Bush" thats got the ACLU or yourself so "outraged".
In honesty I dont see where moving them to a seperate area violated any of their rights. They do the same thing with the kkk types, abortion protesters etc. Is the ACLU gonna take up these causes? How about yourself? They can still scream and yell and wave their placards.
They werent their to have discussion with Bush, they were their to make a schene and get noticed by reporters. They got moved out of they way and now they go to the ACLU to help stir up the publicity they missed out on.
They arent going win in court.
So imo its a whole lot about nothing.
