Is it permissible to bury a suspect in an armed attack in a separate grave from other Muslims as a warning to others?

Summary

An order by the ruler to bury an armed attack suspect separately is permissible when it serves as a warning to others not to repeat the act, provided it is subject to public interest (maslahah). The scholars did not address this case specifically, but it is likened to the view of burying sinners apart from other Muslims and to the Prophet's refusal to personally lead the funeral prayer for a man who killed himself. The action is not contrary to the sharia.
