This is what will happen to Colorado when it begins to attempt to put in place laws and regulations and ordinances regarding legal marijuana.
The Fed will send letters to those who the state and the people were tasked to convert the general wish of the people into concrete proceedure. In those letters state officials will be subtly threatened in that their signitures, their efforts, their meetings to effect the new order can and will be seen as collusion with drug manufacturers and they will reserve the "right" to prosecute in Federal court.
Any confusion that the people or state officials have over the new law will be leveraged by the Feds who will find obscure federal or even state law that conflicts with the general understanding of the new will of the people of the state.
New proclaimations will be made known, even if the promises are toothless not all of them will be and therefore landowners and landlords will be informed in one way or another that they risk their ownership of that land should the Feds find marijuana growing on that land or in those buildings.
Banks will be reminded of all of the anti-terrorist and RICO standards whereby irregular deposits or withdrawals are to be brought to the attention of the feds. Excessive cash deposits are to be noted, and tracked.
Factions within the state who have made it known that they do not approve will be contacted by the Feds,this includes enforcement organizations throughout the state and they will be encouraged to bring the Feds into the picture at every opportunity and there may be, according to statute, offers of compensation - civil forgeiture going in part to the organization that cooperated with Federal law enforcement. DEA agents will infiltrate loosely grouped growing conglomerates - such as co-ops, growing advisory groups, coalitions and the like whereupon the Fed will make every attempt to make examples of minor infractions of the statutes. School zone busts will be sensationalized. Children found with pot will be made very public, Editorials will be written with the message of rethinking the law and ad hoc "studies" will seek to demonstrate that marijuana use is up and that useage will be linked to everything from drops in average grades to excessive purchases of pornography and violent video games.
Invariably someone will take it upon themselves to abuse legal limits. They may steal electricity,they may polute in some minor way, they may have children in the household and the feds will attempt to publicise these events. The IRS will be involved as much as they are legaly able where money is in any way changing hands. Any pot growing vectors i.e. hydro shops, grower's exchanges, farmer's markets will all be put under enhanced scuteny by the Fed if not the IRS.
All of this will be kept either very low key or only the most heinous looking offenders will be made public. The guy who grows 7 plants that are huge and also has a collection of vintage shot guns will be villified. Rape, theft, child abuse fires, armed robbery will all be linked no matter how tenuously to the growing, or transference of marijuana. Every occurance of a federal bust where other more harmful drugs are found iiin the same household will be publicised. ineveitably some marijuana "king pin" will be aprehended and pictures will be published of large collections of automatic weapons and bags of marijuana will be displayed with some reference to the new laws being key to these new abuses and the demise of regular, god fearing society. Auto accidents will be linked to marijuana use, child abuse and neglect will be linked as well.
This is a dangerous thing for the current federal government and it must be reigned in, not only within the state but in order to ensure that other states will not follow suit.
It may be that certain federal grants to the state will be made provisional on strict ordinances, money may be witheld, assistance for the poor made conditional and as before, state and city officials will be harassed. The confusion as to who has the ultimate authority will be expanded where local DAs will be forced to side with either their own state or the Federal government. California was forced to bring this issue to it's own Supreme Court, and after that court made it very clear that localities were to uphold state law and not federal law, those who believed that marijuana is a fundamental evil still ignored Supreme Court rulings.
Venues for federal trials will be distorted in order to curtail jury nullification and the worst possible light will be cast on the state itself. California was portrayed as a slacker state, a doper paradise where nothing ever getsdone and everyone flaunts the law and this new picture of the state will be perpetrated by the fed.
This is all very sad, this is all serves to lend credence to the right who believe that the Federal government all too often exceeds it's Constitutional authority but it is what I believe will begin to happen in every legal state even as it has in every medical marijuana state.
The only answer is to continue to make headway state by state and to charge officials in those states with their duty first to their own state and then only after that, to their federal government.
