Well, I think even the evil or malicious megacorps would generally send Transhumans back to the virtual world if there was any hope they could be convinced to accept it. Its the most effective way of control. If they withhold it, the Transhumans might rebel or decide they don't need it so bad.
I think the biggest risk to our intrepid Transhuman Police Officers is becoming useful. The more useful they are, the more they are dragged into the real world. The more they are in the real world, the better they function and thus become more useful. Eventually, those ones can't go back, whether they want to or not, because they're too busy Saving the World (or at least the virtual world). They may occasionally get vacations back with their friends and loved ones in the virtual world, but they know that they can't stay.
I imagine that promotions would be more likely due to disability and mental trauma. Those Transhumans that know too much to go back to the virtual world permanently, or that are too unstable from their experiences in the real world to function properly in the virtual world, yet are too crippled to continue on the front lines would have to be housed somewhere. Might as well put them in charge of simple administrative functions and training of the newbies, since they're not much use for anything else. While some megacorps might find it more expedient to kill them off, that risks disposing of some vital piece of information that that particular Transhuman knows. As they've basically won, that risk is fare greater than the efficiency. Plus, wouldn't most supercomputers be more paranoid of losing data than they would be of achieving ultimate efficiency? The sentient ones, the ones that evolved beyond the calculators, the fear of losing data would be equivalent to human fears of senility.
Lasers and Treason...way to be subtle. Might want a less obvious knockoff name, since its not a knockoff. Sequel, maybe. Knockoff, no.
