It's definitely not just Waltham.
Sadly, it's the world we live in. The internet allows irresponsible people to disrupt society by threatening violence of all kinds. The best plan is to have a plan. A text code that means a family member is safe, a safe place to meet in case of an evacuation that the whole family knows, cell phones that are charged but put away during the school day with very strict rules for kids that the cell phone is for emergencies only, etc.
But most of all, what parents can do is instruct their kids in internet safety. They can teach their kids about the cost of a hoax bomb threat. It takes law enforcement away from real emergencies while they search for bombs that don't exist. School is disrupted, court proceedings are cancelled, surgeries are put off and patients sometimes have to wait while a hospital is cleared. It's not funny, it's not harmless. It's costly on many levels.
Here in Hawaii we've been told to prepare for possible nuclear fallout from a North Korean bomb. Most likely there won't be a nuclear bomb that reaches us, but there very well may be nuclear fallout and radiation that travels on the tides or wind, and possibly tsunamis or earthquakes. We've been issued a warning that we should prepare for up to 14 days inside in a secure room with plenty of supplies. Each month on the first weekday, they test a tsunami warning siren and wow is it loud. But for the next two months, there will be no test warning. The authorities have said that the next siren we hear will be a siren to announce an actual nuclear event, and we will have 12 to 15 minutes to get into place. There are no bomb shelters, and even if there were, 12 minutes is not enough time.
So, we're prepared, and we have our emergency kit assembled, and our spot in our house chosen, but we're not living in fear. We're going about our day, while remaining alert and smart.
I think that's all anyone can do. Teach our kids, stay prepared, and live peacefully.
