Admittedly this is a congested piece of airspace, but it's bloody frustrating that these accidents keep happening! Especially when there is relatively cheap technology out there that would help prevent it! Google Zaon MRX or Monroy ATD, something like this set up to let you know when there's traffic within 1mile and 500ft would be just the duck's knuts as a backup to VFR. All for less than 1k USD! Bloody cheap compared to what a crash like this costs, in $ and more so in lives!
It's not the only answer, but it's a start! We can't afford to just shake our heads and carry on doing what we've always done, and accept that every now and again there's going to be a tragedy.
