Thank you for a well thought out reply, you're correct, something needs to be done, and quickly, but there are already laws in place that would be effective to a degree in either preventing many of these tragic events such as the southport child killer, and many,many similar nutjobs, warning signs were plain enough to see, but as you rightly state, ignored, misinterpreted, had their been cohesion and action taken by those who knew of the chain of events that led to the final act of crazed psycho carnage, it could have been averted.
imo, it's not helped by groups of idiots who actually appear to think these crazies are simply doing no harm and it often seems more important for them to cast their twisted views on others for stating the perpetrator was colored, an illegal immigrant or non white, or pointing out the fact that white people commit crimes too, maybe that would change if their child was repeatedly stabbed in the head.
and those that have the powers of law seem reluctant to enact those laws, either for fear of racism, or even more concerning,,, they are part of it, as has come to light in a recent rape gangs investigation.
until these people are eliminated from society it will not only continue but get much worse.
To pick up on your comment on "better funding" 100% agree, but where there's cash there's corruption and there's no group of corrupt people greater that government, of any political denomination.
maybe changing that might be a start, but of course their is no guarantee whatever replaced it would not be equally corrupt. the corrupt will keep playing their game, the pawns will keep taking it until the final straw breaks the back of the camel and chaos will ensue, helping nobody.
I guess humanity will implode at some time in the future, largely by its own progression, and nature will no doubt try and rebuild from what's left, it has more time than we can contemplate.
I don't like what's happening, but short of voicing my opinions not much I can do about it, especially given the time I have left.
