Just did a search on bing - this site said that police were preparing for a crowd of 10K:
“Police have been preparing for a crowd of more than 10,000, according to ABC 30, and anti-Trump demonstrations have already begun outside the arena. It is likely that many will be turned away at the door due to the enormous demand. According to The Fresno Bee, Republican activist Michael Der Manouel Jr. says, This is going to be the biggest political event in the history of Fresno.
