Is it possible that charges could be brought against them for some of the recent funerals they've disrupted?
This seems like the simplest way to stop them.
The key to this is to have lots of camcorders taking video of the protestors (if there are 100 protestors, then 10 to 20 camcorders might be able to provide enough coverage). The camcorders hopefully will deter the protests from being disruptive. If the protestors disrupt, for example, the funeral procession with foul language, that would need to be videotaped for possible prosecution.
This would be used as evidence. But also, it can used for other reasons (identifying those involved).
Since people are taking video of these people for possible criminal prosecution, the protestors cannot object to this. And it may make them less disruptive if they know they are being filmed.
Evidence is necessary for prosecution. As for other disruptions, if video is found, there should be no problem with proceeding with prosecution. Or provided there is evidence for prosecuting these people. US Dept of Justice is obliged to work on these cases -- since it is a Federal violation.
The videotaping of other people (non-protestors) can be objected to and possibly have the camcorders seized of the protestors. They would not have a right intruding into the private lives of people. They are the ones making a public protest, and must have permits for "the right of assembly".
I have heard that people that might break the law are less willing if they know they are being videotaped.
But these lunatics may ignore the videotaping because of their extreme beliefs.
So the videotaping is a means of protecting people and helping bringing law breakers to justice.
Some Freeper lawyers can comment better than me. But the local police department might be able to give better advice than this.
And it is always good to have people videotaping with at least a pair of camcorders -- in case they try to destroy one of the camcorders. Think of this as a military operation where the camcorders are important in protecting and also providing "offensive capabilities" -- bringing the protestors to justice.
God bless!
