Having seen the fuller video of him ploughing into a crowd on the pavement, hitting pedestrians whilst missing lamp posts & street furniture, it doesn't look much like an accident.
Interestingly social media pundits seem to be making an issue of his religion - conversely, I've only ever heard religion mentioned after mass shootings in the USA when the perpetrator isn't Christian.
I’m just waiting to hear what happens before I past judgement. To me the video clearly demonstrates there was intent however afterwards when he’s fleeing he admittedly looks terrified of what’s just happened - not the normal signs for someone who’s doing it deliberately. It will be interesting to see how Russia handles it but no doubt he’s probably getting all sorts of accommodating things done to him!
