First of all,
We really cannot play "whataboutism" with every case involving a black person. That's part of the problem. Black people are not a monolith. Our skin does not define our actions, attitude, etc. We're not all violent even if someone keeps using the word "thugs". And we're not all peaceful either. We are people. And some people will always see violence as a solution to what they consider a threat; especially a physical threat.
As the home/property owner you have rights. And black people are supposed to have the same rights as anyone else. The only time your rights are like legally suspended is when you're in custody. This is why you should always ask "Am I under arrest?" and "Am I free to go?" This forces the officer into a legal question where he has to consider if he has enough on you to justify what he's doing.
In the case of this woman, the officer is on her property. She has a right to ask why he's on her property. She did that. But obviously he wouldn't leave or tell her what police business he had there. Police should never be made to feel like they own the place. You have to defend your property. And you can legally shoot anyone on your property if they have no legal right to be there.
If you are black, especially in certain areas of certain cities, it may be extremely threatening seeing a police officer sitting on your property. Because you don't know why they are there or who they might be coming after. It could have been her, her boyfriend, or someone else in her family. You don't know. And all cops act like all cops are good cops so instead of knocking on her door, and giving her the courtesy of letting her know he was there and why, he just acted like her property was his property.
Do we know for sure she threw something? If she did, no that isn't smart. Obviously. And we don't know everything that happened before that. But we do see an officer walking towards her door. They're on her property. At her home. Do I come to your house to do my job? No. If they had no right to be there in the first place they can't just cry about how they were treated. Now you cannot threaten to shoot the police. However, you can shoot anyone who is illegally entering your home and causes you to fear for your life.
Cops really need to think about what they are doing that is threatening to those around them instead of only thinking about what they feel is threatening towards them. They don't know who has a gun or not and that's understandable. But we ALL KNOW THEY DO have guns and what we don't know is when, if, and how they'll use them. If I had a gun and I was truly in fear for my life I would shoot as many others would. You think, no don't because you think that cops always want to bring people in unharmed. That's not true. Some of them are looking for a reason to kill you and who knows what they will consider a threat or what they'll consider resisting arrest. We live in fear of that; terrorized by that, terrorized by the idea that all they have to do is lie and say that they were in fear for their lives so they can get away with murder. It takes a cold blooded person to do that. They are murderers; those who do. And we're allowing them to walk around with a badge and a gun. White people don't really know how dangerous they are because they don't go around looking for excuses to kill other whites. Why would they? But if they are racist, then they have a motivation to take their issues or hunger for destruction, out on brown and black people; especially when they think that person isn't important, wont be missed, is a blight or drain on society, etc. It makes them feel justified. And in reality they're morally worse than those they're killing.
We're trying to tell people how dangerous they are but it hasn't gotten through because its not happening to them. And since they cannot feel the pain we feel, riots create a pain everyone feels. I don't like riots, and especially not looting, but there's a voice in that too.
