No, the theory of small “edges” where an edge is a statistical advantage however so small.
Given any complex event, the more small edges you can find, the more successful you will be — unless your position is hopeless and there are insufficient advantages to accumulate.

It’s all moot now as Sessions has said he’s leaving it up to the state, unless of course there is a serious criminal enterprise going on. Like organized crime, protection rackets on marijuana dispensaries, certain cartel activities.
