Not possession. He was convicted of 11378, which is possession for sale. The new charge is just a possession charge. I'm not surprised he got off on that new one, but I am amazed that you can be convicted of sales and not do a single day in jail - he was managing the apartment at the time of the conviction, and he was never gone from here. So much for time served.
If you go on Google, you can find all sorts of information on mandatory sentencing, both federal and state. I can't find the link that showed the actual mandatory sentences for sale of controlled substances.
It is easy to say "just move," but that is not a feasible option for a lot of people here. Many of the tenants have been here for years, and they are under rent control. This used to be a really peaceful place, and now there are weirdos running across the yard constantly when it is supposed to be private property. You would think the landlord would be concerned about knowingly employing a convicted drug dealer as manager. Liability issues or something. Personally, I don't care if the guy wants to sell drugs, as long as he isn't bringing his customers here.
Anyway, thanks to those of you who are trying to help. I guess we just have to bide our time until he inevitably slips up again.
