Why are they putting 11 humans on a boat when 1 or 2 would be enough to get it where it needs to go AND you'd lose less if they get killed.
getting it where it needs to go when you reach solid ground is where you need humans. boating is usually the easy part. underground tunnels into san diego are how it happens a lot of the time. you can look it up if you are that interested in seeing how effective these things can be.
They weren't going to San Diego. They were on the east coast, not west. They were coming from Venezuela. Destination: unknown but if it was going to San Diego, it's on the wrong side of the continent.
And while I'm sure you need people on the ground once the boat lands.. seems kinda stupid to not have the people receiving the drugs supply the Manpower since they should be locals and less suspicious than a bunch of Venezuelans in a foreign land.
Honestly, given the administrations very tight lipped information... I'm gonna think these were immigrants, not drug runners.
