I do think the police were overwhelmed, and allowed too much press access and so on- and the description of the line-ups in which Oswald appeared were pretty lame.
- IF THIS indeed was suposed to be a professional hit, WHY wasn't an automatic weapon or at least a semi-automatic weapon used instead of a cheap bolt-action rifle?
AS it was, one of three shots missed - and that number very well could have been 3 of 3 if the car had started to swerve/weave side-to-side as an avoidance manuever that day. A semi-auto could have allowed several more shots to have been squeezed off in short order - leading me to believe this was a half-*ssed 'hit job' if it was really intended to end Kennedy's life ...
Unacceptable answers as to why a semi-auto wasn't used are in the vein of "he wanted to minimize collateral damage to other persons in the car by uisng a more accurate rifle" since Connally was almost killed too in this effort that killed Kennedy ...
