BTW, I've fired many types of suppressed weapons in many configurations. A .32 caliber exploding round can be suppressed so that with normal background noise it would be difficult to even get an accoustical tracing from further away than twenty feet or there 'bouts. Also, a .22LR exploding round that has been grained for subsonic will be undetectable in outdoor background noise with a proper can in use.
Expressly today - OR also in 1963 (I'm not intimately familiar with 'suppressor' technology)?
ALSO bear in mind that various sets of 'eyeballs' are active in these crowds (the concpiracy types NEVER fail to attempt to 'neck down' or restrict the scenario to a smaller set than what was actually present, in reality, on the day of a particular event).
I will caution you too; The 'Grassy Knoll' theories weren't even in vogue UNTIL made popular via book published in 1964 ...
Here are several questions for you:
1) HOW MANY other assassinations do we know of here in this country where crossing and coincident firepower was used in an assassination attempt?
2) Can you convince me that the shooter in the TSBD building wasn't making half-*ssed assassination attempt by using a bolt-action, single-shot rifle with an inherent (in that configuration) slow firing-rate?
3) IF, as some people propose, LBJ was behind this event *and* his man 'Mac' (whose fingerprint were supposedly found on a box) was indeed the shooter - WHY wasn't a better/faster firing rifle, a rifle capable, of laying down a few more rounds in those critical seconds than the bolt-action rifle that was linked to at least one of the bullets?
