Cheating in baseball? How can a team do it considering....

Players come and go from teams every year. For example, Charlie Morton was with the Astros for their World Series and then pitched against them this year, while in Tampa. You would presume players would have loose lips once leaving an organization, like the Astros, if cheating was so rampant within the organization. Why is it, if this is the case, that players don’t rat each other out? My guess is that every team does it to some degree.

Also, what’s the difference from watching the centerfield broadcast view of the catcher giving signs and video recording it? Albeit, I’m sure you can get a closer up view with your own equipment but the signs are relatively easy to see through the broadcast. I’m not sure how they do their broadcasting but if there is a 5-10 second delay in the program, that would be the one way you wouldn’t be able to use it to your benefit.
