Where I'm from, such people would be given the death penalty, except of course, if they're backed by political bigwigs who finance their terrorist operations.
In that case, they are not even given life sentences, hell, you even wonder whether they were actually caught and arraigned.

The system is broken, and now we are. Nothing is ever straightforward, and people make compromises for the silliest things.
Everyone was to be politically and socially right/correct, and sometimes, this harms us instead.
