Yes Tinpot is obviously itching for a fight so best ignored.
However there does seem to be this assumption by some that anyone who takes drugs, or deals drugs really should not face any sort of sanction. Whether or not you agree with that, its illegal and you know that either as a drug user or a drug dealer.
The comparison with someone who hit his wife, who unfortunately died as a consequence is a facile one. They should go through due process regardless or irrespective of how drug dealers, paedophiles, shoplifters, whoever, are dealt with, having regard to the particular circumstances of their ownoffence.
There is no equivalence between the two ( or three ) offences and it makes no sense to try and claim there is.
