I read that he came with his 9mm pistol fully loaded. Also, he had 2 magazines for his pistol that carried 20 per. So, he had 40 rounds in magazines and 17 in the pistol for a total of 57 rounds.
The pistol and magazines were a magnet to the cops. They saw a very dangerous armed man. They shot him many times. This shows how fearful they were.
15 to 17 rounds
A loaded 9mm Sig Sauer typically holds between 15 to 17 rounds in standard magazines, depending on the model. For example, the P320-M17 comes with a 17-round magazine and can also use 21-round magazines. Some compact models may hold as few as 6 or 7 rounds, while extended magazines can increase capacity to 20 rounds or more.
I understand what you're saying but law enforcement officers are supposed to be professionals. I do understand that their job is dangerous and fraught with perils, but they are still expected to behave in a professional manner and not panic and kill people because they misinterpreted the situation.
Everyone makes mistake simply by virtue of being human, but when most of us screw up, people don't die, at least not immediately as a result of our mistakes. It is not unreasonable to want, expect and demand that they do better in their dealings with the public, including taking care to not infringe upon the rights of U.S. citizens as well as the rights of the aliens they have purview over, even though they are in violation of our immigration laws. That is not a reason or excuse to treat them with brutality or any other inhumane act.
I mean the easiest way to gauge whether something should be done or not as opposed to whether it's lawful or not is to simply ask how you would feel if this were being done to you, one or more of your family members or loved ones. If the answer is that you would be outraged and want to fight, that's all you need to know for you to determine that what they're doing is not right, irrespective of whether it's lawful or not.
Hell slavery was lawful, that doesn't mean it was not a cruel, inhuman, and violent abuse of the rights of an entire race of people and had the things that were done to the slaves been perpetrated against a white woman or child, the response wouldn't have been and in fact was more often than not, to torch everything.
And just one last thing. People who carry and regularly shoot, often carry extra loaded magazines. If they're responsible gun owners and carriers, they also carry hollow-tip rounds which many prosecutors and others have used to try to convince a judge or jury that this meant that they were ensuring extra judicial menace and harm. The opposite is actually true. So please don’t buy into the hype that the number of rounds carried or the type of ammunition used indicates malicious or deadly intent. It doesn’t. For most avid shooters, both are completely normal.
