the first message was very reasonable. it even said there is "no danger". to check with media and authorities. the second said the first was human error.
if i were driving, i would stop the car, call 911 and ask if anything was going on. they would probably say no, then i would be on my way. instead there is now an investigation, and someone who is already having a very bad day for their mistake is going to get punished even harsher...
should we start having trainings about these so people realize the possibility that these will become useful one day instead of getting mad?
