You have a screw loose. For the police, trying to fight the drug trade is one of the most dangerous things they do, especially those undercover. The idea that the police want the the illicit sale of drugs to continue along with the many lives that are destroyed is just some tin foil hat nonsense not worthy of being addressed on this site.
If you decrease the supply of an item in the market place the price goes up. The seller that has the item for sale can name their price.
You don't seem to understand how the marketplace works. Demand is what drives supply, not the other way around. Do you really think the drug lords want to restrict their supply so they can raise prices? You want to expand your customer base (volume) so you can make more money. And there is plenty of competition out there in terms of supply.
I don’t support open borders, just the silliness of trying to build a fence. Will your fence surround the entire lower 48 states? Say we build the wall from the southern tip of Texas to the coast of California. Is that the only way the Mexicans can get into the USA?
How dumb are you? You create some silly strawman and then proceed to ridicule it. Where did I ever state that we should build a fence along the entire US border? Using your logic, I guess the choice is between building no physical barriers at all or building a fence on every square inch of our border. How stupid must one be to come to that conclusion.
Resort to ridicule and start calling people names? Lost the argument.
