Was the dead guy in possession of a firearm?

Was the gun the dead guy’s or the cabbie’s?

[Winniesboy]

There was a firearm in the car, in which there were the dead man and another person, the driver. That’s all we know for certain as yet.

This is interesting....

Mark Duggan was carrying converted blank-firing handgun when he was shot dead by a single police bullet Probe into 29-year-old's death could take six months

He was in possession of a handgun which apparently started life as a starter's pistol or some such, and was converted to be able to fire live ammo.

Whether or not it was loaded or actually able to fire, being known to police as a gang-banger and then pointing what appears to be a pistol at them, is prime Darwin Award stupidity.
