[EAS] WEA is not a super-tweet: NL Police warnings about football match

[Sean Donelan]

The Netherlands calls their version NL-Alert. It is intended for cases of 
national emergency, such as a terrorist attack or major fire, in case of 
extreme weather conditions, and AMBER alerts.  The ETSI, european 
standard, for cell-broadcast alerts are based on the U.S. ATIS CMAS 
standards. So both EU-Alerts and US WEA standards are similar, change some 
terminology such as a WEA Presidential Alert is called EU Alert level 1.

Last night, police sent a NL-Alert to cell phones nation-wide in the 
Netherlands warning about crowds due to a football game in Amsterdam.
Some people received the same NL-Alert on their smartphones 10-12 times. 
Similar duplicate alerts have occured with the U.S. WEA system.

Amsterdam police later apologized, after many complaints from the public 
in the rest of the country.

The police are investigating what went wrong with the emergency text 
message alert system ahead of the Ajax Manchester United football match, 
after some people received up to six warnings telling them to stay away 
from Amsterdam.

The message was also sent out to most of the country, leading people to 
accuse the police of over-reacting.
