Ban of citizens who participate in activities that put countries at risk

I think we should petition to ban or not validate citizenship to those that participate in activities that put countries at risk. Also those individual that are involved be ask to leave or to be extradited to another country. Furthermore all proven activity wether it be false or shown for good cause be punishable. Activities like aietibg and betting, monopolizing, protesting, and holding government officials hostage for personal gain. Also causing riots, false citizenship , and purgery .

I hope this raises awareness of the seriousness of the situation. Also awareness for people's safety that are involved.
