Actually, HMRC like to catch people, pour encourager les autres.
In that respect, they are far less keen on the easy life than other agencies.
Not that far from where I live, there is a quiet cul-de-sac. It is adjacent to some warden controlled housing (although the warden is now remote). The demographic is such that few of the residents have cars, and those that do park them (for reasons that will be clear) on the other side of the complex.
The cul-de-sac in question has become the haunt of drug dealers. The street lights are regularly interfered with to allow them to ply their trade unseen, and the residents at that side of the complex live in fear. The police, I regret to say, have other more important things to deal with. and do not trouble the dealers.
A couple of months ago, the dealers expanded their range. No longer do they just supply weed, cocaine and heroin. Oh no! They have started supplying..... (you may want to sit down for this)…..
Smuggled Fags!!!!
Naturally this major escalation merited a response. Within 2 days of the word getting out that people could get cheap fags from the drug dealers (who had been left unhindered for 18 months before this). HMRC and the Police swooped, and they were arrested.
