see the thing is the ATF requires a CLEO to sign, .
Not sure where you got that info but this is from the ATFs website
Q: Is the chief law enforcement officer required to sign the law enforcement certification on ATF Form 1 or ATF Form 4?
No, law enforcement officers can be compelled to sign the law enforcement certification under Federal or State law. However, ATF will not approve an application to make or transfer a firearm on ATF Forms 1 or 4 unless the law enforcement certification is completed by an acceptable law enforcement official who has signed the certification in the space indicated on the form. See “What law enforcement officials’ certifications on an application to transfer or make an NFA weapon are acceptable to ATF?” for more information.
