I agree Trent, it's scandalous.
Just saw two quite young people who own flats, they are pretty stuck. One was an engineer and said she knew how to get out, how to get on to someone else's balcony, in a hurry, but who wants to live in fear? We hope such a thing won't happen again - but it might.
In their position I think I would let my flat (at tenant's own risk of course, wouldn't try to hide anything), maybe short term lets, enough to cover the expenses,and move somewhere else that's safe. That's all hypothetical, I'm glad not to be in that position.
