My thoughts are that they should focus on basketball and not on making political statements. "I can't win" should be the shirts they wear. They are on "company time" and there is no room for political statements during those times. If they want to go out and protest what they perceive as injustice, they are more than welcome to do so on their own time.
What's even worse is that this was very tacky and extremely unoriginal.
On a more personal levels, I hope that next time they need police assistance, there are no police officers to help them.
Suns should issue a clarification to the Phoenix PD, stating that players' views most definitely do not reflect the views of the organization, and that the organization is appreciate and supportive of Phoenix PD, or something like that. Having said that, it will never happen as Sarver is to the left of Al Sharpton and other lunatics.
EDIT:
To clarify, I don't give a crap about anyone's political views, but the sports are one thing I watch for relaxation. Last thing I want to see when I watch basketball is politics. Had they been wearing "Don't thread on me" shirts, my reaction would be the same.
EDIT 2:
I equate this with a family Thanksgiving or Christmas dinner where a snotty teenager talks about how Republicans are evil and want children to die, while grandpa goes on a rant about about Obama being a Kenyan Muslim Antichrist. Can't even sit through a 45 minute dinner without going into political fights.
