Breaking a leg

I believe that Booth got the cold-shoulder treatment during his escape because his southern line of support was surprised by the assassination. They were willing to help with the kidnapping plot but probably had misgivings on abetting the assassination.

They helped, to a degree, from loyalty, but they all were trying to avoid spending any significant time with Booth because they knew that Union soldiers would be close behind.

Dr. Mudd paid a huge price abetting Booth and the others were smart to not let him stay in their houses.

If Booth had escaped into Baltimore and further north to New York and/or Canada he probably would have had an even more difficult time with southern sympathizers surprised by his decision to increase the stakes with assassination.

I doubt there would have been a parade.
