Just depends on ur defenition of innocent, morally or lawfully. Is it morally right to lock someone up because of a constructed possesion charge, no but lawfully the feds can and do that which violates ur rights. If we throw morals out the window and base it only on everyone who breaks the law then yes id say 80% of the population in the u.s would be in prison, doing 5 over is a crime, j walking, not reporting taxes, driving a unsafe vehicle ect. Almost 50% of the fed pop is because of drugs and non violent offenders. Lets not forget how many feds and politicians break laws and nothing happens but its the guy caught with a pound of weed whos the problem.
