Please share, that is what we do here.
Yes, obviously terrorist attack. What motive would a drug cartel do to target developmentally disabled people? Why would they want to draw that kind of heat?
Pull a fire alarm and slaughter them with long arms, ski masks. It’s a high body count. They wanted bodies, kill zone. Violent action then quick getaway. It was pre-planned, with pipe bombs. Muzzie jihadi scum.
