Wotcha folks, I've been a bit of a stranger for a few weeks, changed jobs, been travelling a lot as a result. Anyway, this whole mowing down pedestrians, knives, shooting shizz is totally by the book as far as I can tell. It's just a theory, but I think TPTB deliberately introduce inconsistencies into reporting, 'eyewitness' interviews, and media timelines etc., specifically to give the conspiracy crowd a load of stuff to get excited about, very quickly. The general public are consistently conditioned to regard those 'tinfoil hat' people as sad losers with no life, who stay indoors too much and would look at anything for as long as it took to find some excuse to regard real life as being made up, but really they are deluded fantasists.
By far the easiest way to make sure these inconsistencies occur is to be slapdash. And that's probably a lot cheaper too. Double bubble. The real money gets spent on making absolutely sure that the public don't get a whiff of the real secret, i.e. the media, including 95% of 'alternative media', are all totally controlled, and on the same page. For a person previously confident in the integrity of their chosen newspapers, tv channels, websites etc., to find out that it's all total horseshit is a very scary prospect, and probably explains why people so easily jump on the strategy of ridiculing any 'sad tinfoil hats'.
I must say, they have done, and are still doing, a really good job of this. It only works because humans in general are very easy to manipulate, much less clever than they think they are, and afraid of not belonging. And have very very short memories.
