I’m sure I could get a gun in Great Britain in a fairly short time, using the same method this putz likely used to get his AK47 here.
Yup. The street works the same way, no matter where you are. If Britain had such a control on their streets, they would not have an illegal alien problem, nor would they have a drug problem... The same forces that can bring in these things are the same forces that can bring in anything.
