Sacco and Vanzetti Trial

Are these men really guilty? Were they found guilty upon some nonveliable eye witnesses, or because the gunmen were thought to be "Italian", or was it that they both didn't show to work.

On one morning of 1920, two men were shot and killed and money they were transported was stolen. Evidence of the killing was inconclusive and unthrorough.
Who would have thought two Italian immigrants working low playing jobs. Whom were very loyal to their cultures and lifestyles, that is the Italian culture. They became anarchists of the United States.

Nativism was big in the United States, now do you think that involved in the trial of Sacco and Vanzetti? Were they judged upon their decent. Evidence for the murder and bulgarary of these two men was inconclusive.
The bullets found on the murder location were never matched and no one ever had a legitimate testament of seeing these two Italian men.
Now was sentenced served or did the ignorance of Americans of the roaring twenties far too judgemental?
