Did Oswald act alone?

[walrus]

He had been at the police station when Oswald was originally booked. So he was familiar with the routine. Oswald was being moved to a prison when he was shot. He was scheduled be be moved much earlier in the day. At the time Oswald was supposed to be moved Ruby was talking on the phone to one of his dancing girls after which he went to a western union to wire her some money to pay the bills.

After he completed his wire transfer he saw all the commotion at the police station
I'm giving you a very brief and generalised time span of his day. You can do a search and get more detail if you have the inclination

I'm not saying Ruby didn't shoot Oswald, we all know he did, I'm just saying actions during the day don't make it look like it was part of a grand plan
