I think threats and any violence (even minor) against politicians needs to start to be taken far more seriously.
I agree that debate and robust criticism is fine and necessary, but there have been 2 MPs murdered in the past decade and now Ann Widdecombe. Keir Starmer has said that he's received death threats- and he's actually suffered attempted arson on his house!, and of course Nigel Farage has said the same. If we want a fair. representative democracy then this really needs to be cracked down on. If people want politicians who are happy to deal with violence and look after themselves, then sure, let's keep going. But don't complain when you end up with a load of corrupt thugs running the country.
