a community may have the right to protect itself, and may consequently have the right to decide that convicts are not permitted to participate in the governing process, but that doesn't give them property rights over the land.
as is so often the case with what we see from indigenous groups when they are permitted to exercise actual power, this is an example of what a government shouldn't do. ever. under any scenario.
and, if i was her, i'd go there just to poke fingers in their eyes and demonstrate that they have no right to decide whether people are "welcome" in an area or not.
