Many of the politicians insulting each other in the chamber are on quite good terms outside of it. There are exceptions, of course, and the conduct of certain MPs can be troublesome - but it is broadly good natured. If you watch closely during PMQs, you can even see the adversarial act breaking from time to time when one of them gets in a good joke about the other. Politicians being killed is clearly unacceptable and I'm pretty sure the vast majority of even very politically partisan people in this country would strongly condemn any kind of violence. However, we don't routinely have much security for MPs when they are at their constituency office, so it only takes one nutter to do something. If anything, it's sadly surprising that it doesn't happen more often.
