Hotels add gun cases to training

Concerts, large events to see increased police presence

The New York Police Department is training hotel staff how to spot gun cases and is increasing security at outdoor events following the killing of 59 people by a gunman from the 32nd floor of a hotel room in Las Vegas.

The NYPD's Intelligence Bureau trains hotel employees to spot suspicious behavior by guests. But Sunday's mass shooting has prompted police to take additional training steps with hotel security and housekeepers because they have what Deputy Police Commissioner John Miller called "the best observation ability to spot something suspicious".
