So you are saying the British government or another government is trying to rig the elections by funding or executing a terrorist attack in London. Oh well if that's the case I do win my bet. But it seems very unlikely.

I'm not pointing to the British government, this is not only happening in UK. Someone is radicalizing this dudes and convincing them to do all this useless attacks to affect public opinion, this dudes may be doing it for their fanatic beliefs but the people that manipulates them may be guided by something else, someone determined to guide the future of Europe, if that's the case they failed with France though, at least by now. Of course I could be dead wrong but there is something that feels so suspicious about all this attacks.

The last 2 terrorist attacks here have been from people born in the UK. Immigration didn't really have anything to do with it. 

but their nearby mosque did, and thats where most of these immigrants hang. read the 9/11 report which obama censored for many years, it showed that CIA saw radical islamic organisations washing money through their local moques to radical muslims.  apprently Obama found that offensive because he made it hidden for the public to see. 

You're talking about something you clearly know nothing about. 

Their mosque's and others in their community reported them to the authorities under suspicions of extremism, that's why they were on a watch list. 

Can we please alter the post title it seems a little insulting to call it a "accident"

Just a shame that putting someone on a watchlist in Europe is the equivalent of meaningless. When UK is out of the EU they should introduce laws that can violate extremists on watch list privacy way more than is allowed by EU law. Tab their phones, Internet, hell insert them with a GPS chip and install software on street camera's to put an eye on these potential terrorists.

A watch list for terrorism is sort of meaningless, seeing as you can't arrest someone until they've broken laws. 

The manchester bomber could've easily looked up how to make a nail bomb on tor, or at an internet cafe and the government are unaware. 

Also there's no real way of stopping people driving their car to go on the pavement and mow people over, unless you ban people from driving cars there isn't really much you can do. 

Correct. Islam is the problem, not immigration.

In France, Germany and Sweden though, immigration is definitely part of the problem.

Current privacy laws in the EU also don't help with fighting terrorism. But the real reason why attacks mainly occur in Europe is because Europe is weak, unwilling to takw harsh measures againat terrorism and quite pathetic even. All the terrorists from Paris to London where known by the police some where even under investigation. Yet they could travel to Syria and back freely and Europe isn't changing a thing and hopes these attacks just stop for some reason. There is a reason why terrorism in the US is a lit rarer than in Europe.
