Difficult maybe, but doable. And again, we're talking about someone who has already chosen to forfeit their life in pursuit of resistance. I think suicide is, all considered, a less effective form of a resistance than other paths - but if it's the one someone has chosen, one may as well go the extra mile and raise the costs as much as possible. Even if it doesn't succeed entirely, any amount of additional cost beyond cleaning your body off a sidewalk is a loss to the death machine of US empire, and the credible threat of future people finding inspiration in the action/copy-cat attempts will have to be factored into decision making as well.
