The jail released a statement that says they cut every man's hair as a matter of safety.

They say they respect his religious beliefs but feel security is more important in this case. 

Here is the full statement:

"The Jacksonville Sheriff's Office is committed to respecting and accommodating the religious beliefs of all our inmates population. However, when an inmate's religious practices compromise the safety and security of our corrections facilities, safety and security must take precedence. The Jacksonville Sheriff's Office has a long-standing policy that mandates sentenced male inmates have short hair and wear no head coverings. This policy is consistent with that of many other correctional facilities throughout Florida and the United States. This policy is necessary to assure the safety of all inmates and corrections officers, by limiting an inmate's ability to conceal contraband and/or weapons. This policy has been determined by courts to be lawful. While we fully respect the involved inmate's religious beliefs, the safety and security of our correctional facility must prevail."
