Detectives have snapped pictures of Rob Ford swapping packages with suspected drug dealers, seized a video that shows the Mayor puffing from a glass pipe, and even eavesdropped on phone conversations that allegedly spell out an offer made to buy that infamous footage.
However, Toronto Police spokesperson Mark Pugash insists there simply is not enough evidence to charge the Mayor or haul him into a police station to answer questions.
"Evidence is not people talking about him (Ford), evidence is not anecdote. You need evidence to charge someone," he says.
"Courts require evidence and you need reasonable and probable grounds."
Pugash categorically denies that Ford has ever received any kind of special treatment from the police.
NEWSTALK 1010 asked Pugash about reports the Mayor was the subject of a police alert in August.
Dispatchers told officers across the city to be on the look-out for Rob Ford's SUV after witnesses called 911 with concerns that the Mayor was not fit to drive.
An officer tracked the Cadillac Escalade to a hotel on Jarvis Street but the Mayor was not in the vehicle.
Pugash says the police would have had no grounds to charge Ford.
"In an impaired (driving) case, if you say 'I drove impaired last week,' I can't charge you with that -- we need evidence."
Pugash says that while detectives still want to speak to the Mayor about his links to drugs and criminals, the police cannot make him do so.
"We have requested that the Mayor agree to be interviewed. He has declined. We are not legally allowed to force him," he says.
Pugash adds that when another investigation into guns and gangs stumbled upon link to Rob Ford, authorities knew how potentially explosive the allegations against the Mayor could be and how much scrutiny police operations would come under and as a result, opted to put top investigators on the case and maintained close contact with lawyers regarding every move.
Pugash insists the investigation was executed 'absolutely by the book.'
"We've made sure that we've dotted every 'i' and crossed every 't' and we can justify what we've done and what we haven't done," he says.
Several new but unproven bits of information about the crack cocaine scandal surrounding Rob Ford came out in police reports released by the courts earlier this week.
For example, there are allegations that 2 months before the crack video story broke, Ford was trying to buy the footage.
The allegations are contained in transcripts of wiretaps of the Dixon City Bloods gang speaking to each other on phones.
None of the allegations have been proven in court.
