Of course. If through your own hard work and observation you can tell what the other guy is going to do it’s his problem, not your.
Now that doesn’t include the Patriots using hidden cameras to record the other teams practice or the Yankees having someone in the stands steal the other teams signals and radio them to the dugout ... those things are still illegal.
I have always loved that the reason the Patriots were caught was that the Jets used their camera, which was being used to do the same thing, to record the Patriot cameraman.
“Now that doesnt include the Patriots using hidden cameras to record the other teams practice [...] ... those things are still illegal.”
Also imaginary...both parts there.
