The Texas Medical Center is not a bad neighborhood and usually has security roaming around. A shooting in broad daylight is VERY fishy.
And I would imagine, in this day and age, a decent network of CCTV cameras, perhaps?
And if there is such a network, I’m pretty sure it was down for scheduled maintenance on the date and time the assassination took place.
Kind of the way that all Police/Fire/EMS radio system collapsed during the school and airport shootings. Imagine that?
