Sad news that four people including a policeman and the murderous criminal who undertook the act was killed.
It seems he took a 4x4, drove it across Westminster Bridge, injuring many people and crashed in front of the exit where many MPs leave the Houses of Parliament. He then stabbed a policeman and was then shot dead.
UK security services had been conducting tests for days like this and it shows how quick the response was put it into action and the inspiring work of the ambulance services, police.
Sadly, you have a few shitstains either in person at the scene making political points for their own agendas and on social media so it's simply a fuck you to them all. Also many people on Twitter naming the name of the suspect who it turns out is in jail - how about waiting for official news than speculating ffs
