Reggie Bush just compared Ferguson to Israel -- suggesting Israelis are shooting unarmed Palestinians ... the same way Officer Darren Wilson shot Mike Brown.
The Detroit Lions star went to Instagram and posted a photo of a man holding a sign that reads, "The Palestinian people know what mean to be shot while unarmed because of your ethnicity #ferguson #justice."
Bush also included a caption -- "No matter who you are, what color skin you have, where you live, we are all in this together! This isn't a Ferguson problem it's a Global Problem! We need change NOW! What happened to humanity? #JusticeForMikeBrown."
