I won’t give credit to “Reverend” Farrakhan yet, for the sole reason that this looked like a professional hit. So, the first suspicion should be to the Mexican cartels. Specifically the Gulf cartel, which considers Houston as in its territory.
What increases its likelihood is that the Gulf Cartel is going through a generational change, so has a bunch of up and coming leaders vying against each other, and unlike their predecessors, they see the border as porous, so no reason not to operate in the US.
Recently, as part of an investigation into four Gulf dealers operating in Houston, a veteran cop was arrested for working for them. Then one of their new cartel leaders was arrested while shopping in a mall in Texas.
And the Gulf cartel has a lot of professional killers, just like how this assassination was done.
I beg to differ. This was a BLM/Nation of Islam inspired hit on an on-duty officer. Nothing more, nothing less.
