It's largely academic who gets "mauled" first. This will be no different from hundreds of other accidents. Sadly there is always the same chain of events which will include the company ethos, EMS Operational ethos, the crews' professionalism, operational pressures, wx, aircraft serviceability, etc, etc. Some of these score positively, some score negatively, clearly this outcome had an overall negative score. Sometimes pilots have no idea whether they avoided an incident by a whisker or a country mile, but getting all the factors you can personally control on the positive score sheet is always sound advice. That's why only a fool or a journalist will say they know what caused it while the wreckage is still smoking. It's because they confuse knowing what the outcome was (helo hit building - we can all see that) with knowing what truly caused it.
