Actually that rumor of 750 New Orleans police going on vacation to Vegas has been debunked. It was 40 police and first responders who had worked around the clock for days. Trip was donated by Vegas businesses.
This was not a rumor - it was a lame cover up excuse by local politicians to explain why there were about 750 fewer police on the force than there were on the payroll.
Of course there never were 750 police officers taking off to Vegas because there never were 750 officers - they were phantom workers and the New Orleans PD had to have an explanation why there far fewer police officers on the streets than the employment rolls showed.
