Other people's safety also is necessary. That is, of course, you do not want to go and kill somebody, but your country also should be protected. Generally, all countries have forces which are called defense forces, but nobody has offense forces. There are defense ministers, and all that. You do not call them offense ministers.
Nobody offends, because everybody is defending only.
But nobody says they are offending, they are only defending. But, one does not say like that. The man whom you say is offending will say he is not doing like that, but that he is only defending himself against possible trouble. He wants to defend himself against future trouble, though it looks like offending. This is what he will say, though you may say that he has made a mistake and that he is offending.
