Obama spoke pretty glowingly about police officers. Right wing media made a very concerted effort to hide that. Through and through, Obama was a thoughtful and deliberate guy, who always seemed to be very moderate by nature, and had a deep respect for the law.
Here are some quotes from Obama. The way he speaks about police, the amount of thought he puts into the way he expresses gratitude and respect, shows a greater level of respect than anything somebody like Trump could ever display. Obama was actually thoughtful and had considered what his words meant.
Obama was never anti-police. History will remember him more accurately than he was painted by his political enemies. When you actually revisit the words of Obama, it paints a clear picture of a deliberate and thoughtful guy. History will look back on a guy like Trump and everyone will go, "Yeah, he was actually worse than we imagined."
