Aye, it could. Like I said, I have no idea of the circumstances apart from he discovered to be thirteen, was on a bike and was seen by a uniformed officer on foot.
To answer you
@Rita_Poon, straight away, I was asking myself from what distance they saw the child, what was their field of view and what time of day.
I noticed it was 3.45pm, so lack of light wouldn't be a factor, but distance or an obstructed view can impact on defined age, height and the weapon.
I would suspect it's been reported over the network, and as per policy, a firearms team have been called to intervene with unarmed officers holding at a distance.
An unarmed officer, if he thinks he's seen a firearm, shouldn't/won't intervene unless there is a genuine risk to life there and then, otherwise it's to contain.
So why have they knocked him off the bike? I don't know as I said. It could be an officer being overly zealous, or maybe the circumstances at the time 'warranted it'.
Now, with hindsight it doesn't look great at all that it's a thirteen-year old boy with a water pistol, but I refer back to the original observation part of my post.
We also don't know he responded to being stopped/asked to stop, if he was. We do not know the size/profile of the boy, what he was/wasn't wearing etc.
Again, it's all conjecture - I'm just trying to think of the potential circumstances that led to the officers deciding to knock him off his bike.
What we've got to hope is that there's enough evidence to prove it either way, and whatever the findings key learning is taken from it and if necessary action.
I understand and appreciate the sentiment that the country can't afford a young boy (of any race) being injured by police on a bike, but we have to balance it.
There are circumstances where you could quite correctly justify their actions; the issue here, is we have no idea if this is or isn't one of those circumstances.
