*A good way for Texas school districts to avoid national humiliation in the future is to establish equity teams in every high school. This was a major demand in the Seattle teacher’s strike, which was settled Wednesday. See Seattle teachers strike ends
**Law enforcement please note: in Texas it’s against the law to interrogate a minor (no matter how dark his skin is) without parents being present.
***Clocks are used to tell time.
