Danger Money?

I have posted a couple of times already about Fathers 4 Justice. Today I read an article in The Observer about fathers' contact with their children, following on from recent events, that mentioned an incident where a man threatened his ex-partner's solicitor that he knew where she lived and that there would be trouble if she didn't leave him alone. A few days later the solicitor's car exploded outside her house, although no one knows who was responsible. This brings to mind something that happened to me about three years ago, when I received a letter at my home address from my client's ex-partner, despite the fact that I was in correspondence with him via my firm. Nothing followed, but there was a clear implied threat: "I know where you are". This was not a child contact matter. I'm sure many other family lawyers have had similar experiences. Perhaps we should receive danger money?
