This is not difficult to comprehend. Individual institutions have their own codes of conduct that differ significantly from state and federal law (sometimes more strict). Additionally, the stardards of evidence required for disciplinary action are different (less intense). This is no different than someone being found innocent in criminal court, but being let go from a job for violating the company's ethics rules. Football players are high profile representatives of the University. When they do scummy things (as in this case) and make the university look bad, there are going to be consequences. Easy solution...don't engage in scummy behavior. Welcome to the real world boys.
