Police Officers help Please!!!?

I was incarcerated on a bogus crime ( better said the crime was waaaaayyyyyy out of my character) which spurred from false-postive narcotic field tests...What are the odds that the police got not one but two false-postives??? (...so far one has come back from the Pensacola Crime Lab as 100% negative for drugs under the 893 Florida statute.) HELP! POLICE OFFICERS ONLY
