Pure crap!
96% of Federal inmates accept a plea deal instead of going to trial, where the conviction rate is almost 100%.
That means about 96% of the convicts Obama released already had at least one felony dropped or reduced.
Unless this “dealing” was something like someone or a team privately growing their own pot and nothing more, it’s going to be embroiled in violent crime anyhow. Now we can argue about whether it ought to be (like Prohibition) but it empirically is. No regulation, obscene money to be made, unpredictable competition, no protection of the law.
