You've GOT to Wonder How Many WEREN'T Intercepted

According to this BBC report, a freight truck was stopped at Dover trying to enter the UK and thirty Uzis were found (along with ammunition and suppressors) hidden in a spare tire.

So, how many got through? I believe the estimate for intercepting drugs here is about 10-20%?

Oh yeah. Disarming the innocent really cut down on the influx of guns in the UK, didn't it?
