I remember reading in a book about Jewish members of the mafia about a mafiosa fellow nicknamed "The Rabbi". He was given this nickname because he tried to avoid killing on the Sabbath. And when he could not avoid it, he would first put on his tallis and pray a bit before murdering his target.

I was reminded of this when I saw this article about a ring of 5 Orthodox drug dealers who close up shop for Shabbos. It seems they would send out messages to clients letting them know not to come between sunset on Friday evening until sunset on Saturday evening. The group of men has been indicted - they have been arraigned this week, pleading not guilty, and most are out on bail.

It's a funny thing, but even way back in the time of the gemara, and later in the time of the Shulchan Aruch, we find that it is common that people very religious can have a problem with one specific vice - and they would be completely trustworthy in regards to everything else except the one area in which they have a weakness. It is strange to call such a group of men "orthodox". Maybe just by being involved in pushing drugs a person has given up on being associated with Orthodox Jews. However, when that is how they act and present themselves, even if they have their one or two vices that are pretty bad, it is not wrong to still call them "orthodox".
