@BrickBack - I know what you mean. Some people think that exculpatory evidence developed in the OJ Simpson trial when they had OJ try on the black leather glove and it did not fit him.
The late Johnny Cochran said his famous line, “If it don’t fit you must acquit.” Although this was a huge mistake by the prosecution because they wanted him to try on the glove, many in the jury viewed this as exculpatory evidence because if this was the glove used in the murders and it did not fit him then he could not have possibly committed the murders.
Unfortunately the jury tuned out the explanation as to why the glove did not fit which was due to the fact that the leather contracts especially when it is moistened.
I think that this is the reason that OJ was found not guilty because the jury did not feel that he committed these crimes.
