There is a fine line between 'Urban Exploration' and reckless stupidity, the only saving grace is these knobs have even been stupid enough to show their mugs on this vid, so if the tunnel authorities would like to press charges for 1) Breaking and Entering and 2) Theft (not to mention Wilful Damage etc) then they at least have some nice hard evidence...
Did you notice by the way that the fire extinguisher lasted around 30 seconds? Not much fun to play with but a life saver when used for it's correct purpose. Let's hope the extinguisher has been replaced so that if the poor sods who work there actually need it to help fight or escape a fire there is one to use.
The only thing I can say in defence of these knobs is that if the tunnel people had been doing their jobs then the tunnel Plods should have been there as soon as the gates were breached, it makes you wonder how good the surveillance systems in the tunnel really are !
