You're nicked, son!

Should the identity of someone who has been arrested be made public?  Lot of discussion about this recently, not helped by contradictory statements by Ministers. So - what do you think?  In my opinion the answer is "no" save in exceptional circumstances such as where there is an ongoing situation of which the public should be made aware.  The basic argument in favour of naming people who have been arrested is that it may result in witnesses coming forward - but it seems to me that this is a further example of the worryingly prevalent police approach of "arrest now - hope to find the evidence later".  Once a person has been charged of course, that's a different matter - they should be named.
