The Disruption idea does look interesting, as you could effectively "lock down" things.
There's also a big BUT. Law enforcement entities sitting near the drop-off point of illegal commodities aren't working very well and won't even if the lockdown becomes possible.
They shouldn't sit still and go get the job done instead, patrol around Liberty, that means Texas, California and Colorado, too... that way traders are going to be much safer, smuggling harder and overall public reputation of police and navy would rise...
