Cars should not be allowed so close without some mandatory checks even when this does all calm down...? Even a simple stop and visual check !
Surley it must be difficult to hide gallons and gallon of petrol and gas cylinders.
I am not en expert on car bomb technique but would not road calming/bumps 100 yds away on the approach roads help and be cost effective ?
Would not a severe jolt set a bomb off ?
...there again if they pop 25 mile down the road they could drive in the back way to Stanlow Oil Refinery, leave a bomb and be out of the country by the time it went off!
.....no security on the side lanes and the fence is all hanging down...only contains 30% of all UK oil !
