maybe the first purpose was to provide justification for “war on drugs” expenditures - ‘see there are massive amounts of drugs coming into the country and we need all these invasion of privacy laws to protect you from these drugs and we need all these fbi agents to track the drugs and we need all these swat teams to get the druggies arrested and we need all these judges to put the druggies in prison and we need all these prisons to put the druggies in and we need all this welfare to support the children and wives of the druggies in our druggie prisons and the welfare wives will vote for Democrats as long as they remain on welfare because of course it’s Republicans who are fighting the drug war and putting you all in jail, not Dems you see.’
