While that's true, I'd be properly pissed off if I were a cop, and someone just strolled into my station with a gun and plopped it down on a table.
Let me just reiterate that this all could have been avoided had he just said that he found a gun somewhere when he called the police station he was taking it to.
It happens here all the time, actually. People find firearms when going through belongs of relatives, in old storage boxes, that kind of thing, and don't know what to do with them. Many just take them by the police station and drop them off instead of trying to sell them.
In Richmond I got rid of one of my pistols and had a bunch of leftover ammo. I just walked over to the police station and asked if they could please dispose of it for me. I then handed the desk clerk a bag of ammunition and went on my way. No questions, no ID, just "Hey, this stuff can be dangerous, can you take it?"
The guy could have handled it better. He could have dialed 999 or called the station's non-emergency line as soon as he discovered it was a firearm. Still, at that point he had brought it inside his home so he still might have gotten charged.
The problem here is a lack of personal responsibility. The UK seems so worried that people will make the wrong choice that they have tried to legislate away
any choice at all. What they are saying with this law is that anyone who touches a firearm intends to commit a crime.
Touching a firearm is a crime
You intended to touch it, therefore you intended to commit a crime.
People already have little personal accountability or sense of responsibility, they go through life expecting others (companies, governments, the police) to keep them from harm and protect them from themselves. Most warning labels are so idiotic that it makes my brain bleed, but they are there because someone was dumb enough to use a hairdryer in the shower. Here you have a guy who has taken personal responsibility for making his neighborhood safer (yes, I know it was in his garden, but you never know when someone will come back for the gun), and he's prosecuted as a criminal. He's even a soldier! The state trained him how to handle firearms for fuck's sake!
