[music] >> We are at the firearms lab at Lambeth today. So, the team here they take all firearms that police recover, all casings that police recover, and all bullets that police recover. They forensic examine them find whether guns are linked across series of shootings. They look at >> [music] >> identification marks to see what gun was used in particular shootings. Each one we recover gets test fired in in the range here to check its viability, check that it's a legal weapon. [music] Sorry. What I really want is to you get communities on [music] board to get people reporting that they see firearms, they hear about firearms, or there's [snorts] any intelligence [music] that they could give to us. But, if you do see a firearm, please don't touch it. Please call us at the earliest opportunity, and we'll deal with it and hopefully find the person [music] that had it.
