One is school security systems. When we invest in something we do a lot of diligence. Rather than relying on major media as a source of knowledge we dig ourselves and spend a lot of money doing so. So if we are investing in school security businesses we want to know what would possess some one to go into a school and shoot children. We’ve also looked at weed investments. A reasonable analysis here would involve learning about any negatives from legalization including higher crime levels. I can’t find anything compelling on weed given the history of money gone up in smoke here and the movement of non legit weed dealers into other drugs (fentanyl). But I digress from the weed shooters. You can research almost every mass shooting in history in online data bases. You can also pay folks to dig through social media posts and other sources about every one who has been a mass shooter. You can also get a lot of data from law enforcement sources who focus on this as well. Usually they are glad to share the work they have done. Prior arrest data is also helpful. I am always amazed the news media doesn’t look into prior records much. Due to the major media bias to continue to push for legalization of marijuana the tie between mass shootings and weed is often downplayed or even removed (parkland is the best example). There are some sources on the internet that have done a decent job covering the tie, but the weed industry and its lobbyists seem very quick with the rebuttal pieces from experts. Based on our research, which we pay for, I can assure you there is a big correlation to school shootings and other violence and weed use. If you take the shooter databases and actually dig on your own your can find many of these ties even though many major media companies don’t cover it. Putting hallucinogenic drugs into developing brains, especially folks with other social or prescription drug addictions, has deadly consequences. Anyone who tells you that weed psychosis isn’t a threat probably hasn’t had a fried or family member go through it. I don’t share firm research but there are many places online you can piece the drug use of specific shooters together using the online shooter databases and other sources available to any one with a mouse and keyboard. I am very, very confident in my 6 of 10 statement.
