@Lash,
OJ was never cleared in any police investigation. He beat the rap in the criminal trial, but in the civil trial the jury decided he did kill his wife and her boyfriend Ron Goldman and said he had to pay $33 Million. This conviction directly led to OJ associating with shady celebrity memorabilia dealers to avoid having to pay the civil judgment. These shady dealers then double crossed OJ, which led him to retaliate by "taking his stuff back". Guns were involved in this process, nobody was actually shot but one of the shady dealers had a near fatal heart attack the next day from the stress. As a result of all this, OJ is now serving a life sentence with the possibility of parole after nine years served, (2017 at the earliest). So basically, OJ ended up serving time for the murders.
Relationship between the OJ case and Hillary are solely in the mind of the right wing internet dwellers, but then these are the people who decided that Hillary had a sexual relationship with Vince Foster before they later decided Hillary was a lesbian through and through, so these things are always fluid with them.
