Lawyer lips are the most stupid invention of a whole heap of steaming idiocy in the world of cycling in the last twenty years.
As Ian points out, the wheel is not much more likely to come out. When I was younger & unused to qr, I managed 20miles into the Peaks with a bit of roughstuff thrown in with a qr open
Now, though, I do a quick visual check of my bike - brakes, tyres, qrs - before getting on it. If your bike park is badly lit, that can be tricky, but it's always worth finding out sooner rather than later.
All that said, I think it's a really unpleasant thing to do, and I hope the scrote concerned meets a suitably kammic fate. And I'm very glad you're OK.
