The CNN article doesn't say they are false, CNN is just quoting the National Police. It's also a vague quote. It could be a translation issue, but they don't explicitly deny that either of the shooters were police officers. "Our Institution" could mean that the officers were not representing the agency. It could also mean that they are former police officers. Everyone should be skeptical, until we get more facts, I totally agree. I'm just passing along what one media outlet is reporting, not endorsing it as fact.
