50 cop cars on I-45 southbound just north of 610 on the northside???

Was just driving down 45 from Dallas and in the span of 2 minutes saw 10 cop cars fly by with their lights on. Then, in the parking lot of the Texas Barber College on 45 before the Crosstimbers light, were like 50 cop cars all with their lights on. It was nuts.

Did anyone else see this? Or know what’s going on??
