What we are saying is a witness saw a gun and reported it.
No waving it about then? No pointing it at anyone?
Are we clear on that? Can we all agree that those saying he was waving it around or pointing it at people are simply making stuff up?
The witness saw what he or she thought was a gun through a window at night. For reasons known only to the witness, a report was made to police that a 'black male' was in possession of a gun inside a house.
Handguns are illegal in England so there's no innocent reason for having one.
Handguns are illegal in England but many types of BB guns, some shaped like handguns, are not.
If the boy looked old enough to be a threat with a real gun then why not assume he was holding a BB gun? Does 'black male' figure in the assessment of the threat?
If he looked young, as in the photos that were released, then why make the call?
And why did the police not ask for a physical description of the person in possession of the gun - approximate height and build for instance, that would indicate to them whether they were dealing with a child, an older teen, or a grown man?
If they knew they were dealing with an individual of short stature who might well be a child, then their response was completely inappropriate, and arresting what they knew was a child of twelve even though they had determined that it was a BB gun was completely outrageous.
Price attended and secured the scene. Then the who, why, how, what questions can be asked. Ascertained that it was a BB gun that looks very muck like a real gun.
But the who, what, how, whatever, questions apparently were not asked and the boy, aged twelve, was arrested. Or they were asked and the boy was arrested anyway.
The securing of the scene you crow about involved pointing laser sights at the heads of small girls and their mother.
As a result there are lots of very appropriate questions that must be answered at the highest level, because what was done in the name of law and order looked like police who were out of order bringing the law into disrepute.
Nobody wins when this happens.
Good job met police.

This was a disaster from every possible angle.
Alternative - person sees gun, phones police, police say "ooohhh no. We know you said it's a gun but it might be a Wii controller or a remote control. We'll leave it, just in case"
Again 
Alternative - report comes in, police ask pertinent questions such as demeanour of gun wielder, location, presence of others, height and build and other physical descriptors.
Also pertinent would be a question about how good a sighting the reporter got.
This is all because it would be a huge pity if you were to find yourself with a red dot on your forehead over a game of wii or simply because your TV remote needs a fresh battery.
Sauce for the goose will eventually be sauce for the gander.
Do you want to find yourself living in a police state? If you believe it wouldn't be all that bad because there would be fewer criminals on the streets then perhaps ask yourself how the police would determine who was a criminal before they started shooting, and how comfortable you might be about their calculations.[/quote]
Give over.
I don't care who was hiding the gun - man, woman, child, martian, dog, black, white, red and yellow with pink spots. What matters - gun. That's it. No, people shouldn't assume "oh it might be a BB gun". It looked like a gun assume it's a gun.
If you saw a child being dragged screaming into a car and the car driving off would you think "omg. That child could be being kidnapped, phone the police" or " oh. It looks like a kidnapping but it could be a child having a tantrum and dad's just pulled them into the car so I'll leave it, just in case I was wrong"?
You're being ridiculous. Everything that happened after the passerby saw it was as a result of boy having gun in view of a public street. No, the police shouldnt have ignored it. It might have been a real gun - London has issues with drugs, guns, crime and yes, involving 12 year olds with county lines etc.
Don't want armed police showing up? Don't give a child a BB gun that's indistinguishable from a real gun.
