Note sure if it’s just another statistical bullshit report or just poorly written – in regards to the locks I’m reading it as:
73% of bikes stolen were secured with a cable lock.
5% of bikes stolen were secured with a D-Lock
So presumably 22% of bikes stolen were either unsecured, stolen from the owner by force or and/or other (perhaps secured within a garage but not otherwise locked).
I’ve always believed in the core of it, thieves are lazy – that’s why they spend their lives risking their liberty to ‘earn’ a pittance – because it requires little actual work – which invariably means they’ll follow the path of least resistance – that’s way even in 2015 when 99.9% of people consider a burglar wailing in the middle of the night an annoyance rather than a reason to call the police they still have an effect – a burglar when presented by 2 houses, 1 with an alarm and 1 without will rob the one without.
Same goes for locks, D-locks might not be 100% secure (nothing is) nor are cable locks completely useless – but one’s easier than the other so lazyarse thief will go for the easy option, even if the bike with the d-lock might be worth a bit more.
