You shouldn't be so quick to judge a crew's response to a situation if you do not know all of the details. While scene safety is always of the utmost importance, perhaps the scene did not initially present itself as a danger. Hearsay never conveys a true account of an incident. Hindsight is always 20-20. Instead of being so quick to judge, be thankful the crew and patients are doing well, and many positive lessons were learned.
