Yes, there are really two ways of thinking about that. One is that it starts as a bottom-up process in which you engage in low-level interactions. The alternative mechanism could be a top-down thing, in which you go through anti-terrorism legislation very closely and say that right now, as it stands, people who might be advocating hard-core vandalism and might accidentally injure somebody are treated the same way as a terrorist group that is actually advocating shooting people directly, putting it within the legislation that there is that finely grained detail as an opening statement to groups that might be less willing to participate.
I recognize we're talking about the difficulties of making a bridge between law enforcement culture and activist culture. I'm not under any illusion that it would be easy to do, but there are ways to make a venue for that kind of narrative to develop.
