From my perspective I believe the implementation of the tactical firearms unit has improved the overall efficiency of the police department, considering how the system was before, where in most situations you'd have community members become S.W.A.T. and begin lingering around the department doing literally nothing before (most likely watching memes on television or tabbed out), in most cases which was comical as they'd mostly complain about not being able to respond unless called upon. Now with the recent changes I've noticed a lot more professionalism when it comes to handling certain situations in which your standard patrol officer wouldn't normally be able to handle by themselves. I believe one thing most officers forget about having a competent force on duty who is ready and capable of responding quickly, is the ability for combat readiness should the situation arise, which is something that a lot of members are viewing as being unrealistic as they're carrying around weaponry on their person whilst patrolling, I personally don't have an issue with the matter, as now and I'm sure you're aware we're dealing with some intensive shootouts which can sometimes get out of hand, sometimes to the point where we're dealing with explosives.
With the current police force continuing to develop, as we're getting new officers signing up and getting trained to deal with situations which will eventually occur during their career path, I've noticed that newer officers are adapting better to the change of the tactical firearms unit since the update, more than that of more experienced officers, considering however that this is still my opinion and not solely based on fact, I believe players are still in comparison to how the old system fairs in comparison to the new, and are solely basing it on either positive or negative experiences depending on what happens. My last point to be made is the civilian point of view of the unit, as you probably know, I don't get into much shootouts as a civilian so the majority of my knowledge of criminal activities and responses come from the communities feedback. In most situations in which I speak to civilians about the tactical firearms unit, they don't respond negatively simply because they're players who can handle them simply using flanking and or manoeuvre tactics which is fine, as this fault can lead to the officers in control of the surrounding perimeter and those commanding it, which is the case most of the time as most members of the tactical firearms unit reside inside buildings due to raids happening there. In conclusion I believe over time the appreciation of the unit will increase over time and like anything grow better and better. It's simply a matter of time and patience.
Once again this is only my opinion and not plastered with facts.
