Not something as serious as this, coppers have been charged with offences and lost their jobs in recent times for such breaches of confidentiality, and I'm sure the ones on this case would be mindful of/or have been reminded of that.
I would imagine that police wait for reports from the relevant experts before releasing details of this nature.
Not "it looks like she's been hit over the head with a hammer Sarge, best call the Daily Mail and let them know"
The bi-folds are only held in with screws, get the installers back to whip it out. Then sort the brickwork, then put back, otherwise this will haunt you forever!
I would say it's purely cosmetic, that's what timber does, and shouldn't affect their ability to keep the fence up.
If you've put them in concrete, that's where your point of failure will be.
A picture would help. It wouldn't be the end of the world to put the brickwork right, and would probably cause less hassle overall than your proposed solution would.
