Imagine you're a solo on a job, you just got that brand new Trusight mod for your HiPoint, you've made sure your mag is full, you've cleaned your weapon religiously and now you're off to stalk your target to get those corporate dollars. You step inside of the club they're at and the alarm goes WHEEE OOOO WHEE OOO. They run outside because they smell trouble, for some reason.
Now, this was okay with the way the system worked before because there was a very strong emphasis on ambient population, but right now people are very likely to take advantage of detectors in a way I don't believe was intended by their creator.
Solution? Get them out of the mix entirely, please. I don't think they're useful for anything beyond getting firearm users frustrated that the entire club now has eyes on them because there's nothing to stop that from happening.
