I couldn't watch this for very long. IMO Jeff Buziak is doing much more harm than good in his approach to obtaining justice for his daughter. He's a grieving parent, but there's a reason we don't turn crime-solving over to grieving relatives, in our society. In addition, I think he's troubled by guilt that he admits he feels, for not having saved Lindsay. Perhaps to escape from the feeling of blame he places on himself, he's turned his focus to trying to blame the police, and her boyfriend.
For whatever reason, IMO he's doing the exact opposite of a good police investigation by publishing, and encouraging others to publish, every wild theory and accusation.
In contast, good police investigators don't reveal who they suspect, so that they can do surveillance, or probe through non-threatening questions, or even run a sting.
Good policing means following the evidence: gathering it, maintaining it's integrity, analysing it, it's the only way crimes can actually be solved, and successfully prosecuted. Anyone can speculate with wild guesses, based on the plot of their favorite soap opera/ mystery novel/TVshow.
Even worse, Buziak has published the names, photos and home addresses of various people he personally believes have something to do with the crime, none of whom have been named as suspects by police, some of whom have been officially declared as not suspects.
In contrast, police in Canada know they will get their case thrown out of court, if they give any appearance of having violated an accused person's right to a fair trial.
I believe police know a lot about this crime, and they have hinted at that through their statements. They want to catch the people who ordered the hit, not just the killers. They need to bring a case that will survive the stringent test of the court system, not just yell at someone in a parking lot. They may have to wait a long time for the right circumstances to set and spring a trap. These are not fools, who did this.
But now, even if police get sufficient evidence to charge the real culprits, the defense will use all of Jeff Buziak's very public accusations to try to get their clients off the hook. The defense will point to all the other's he's accused, as equally likely suspects (just like Charles Merritt's defense is trying to do in the McStay case). His insistence on police incompetence may also be used by defence lawyers to cast doubt about the quality of the police case.
