The TV programme. Crash investigation "expert", one PC Mick Whittingham (he was a mechanic before joining the Force, so he's an absolute expert, right - holds up a H4 bulb and declares "The brakes were on at the time of impact: the filament has bent rather than shattering, so it must have been hot rather than cold". Yeah, right. An R6 on a two-mile straight went up the arse of a tractor - there's a 100m darkie from a tyre, so it's pretty fucking obvious the brakes were on, OK. Not that, though - for how long have Yamaha been fitting halogen bulbs in brake lights? I must confess, I got a bit shouty at the telly. Expert forensic crash investigator, my arse.
