The title of this article says "11 armed guards" but in the actual article it says "security department made up of at least 11 people. Many of those are police officers, who are presumably armed."
So... which is it? 11 armed guards, or 11 people in the security department, of which "many" are police officers who are "presumably" armed. How many is many? Are they armed or presumably armed? Do your basic journalistic work and stop publishing made up stories. BS
