>In other words, don't tell them "give a criminal a second chance." Tell them that many people with criminal records simply shouldn't have them...
That's a very interesting approach, but I believe a hard sell to potential employer. As true as it may be, an employer is more likely to appreciate the individual who says this is my background, this is what I learned and this is my vision of my own future...rather than, it's not my fault, I'm a societal statistic.
In fact, despite the ideas of US prison overcrowding and for profit drive conviction rates...I'd argue the opposite, that it's very likely the employer has already hired individuals who have committed various "crimes" and could but simply don't have records.
I know it's stance but all you need to do it look at the number of reported crimes (serious, not victimless like many would argue about drug possession) and the total prison population.
Example:
prison population = ~ 2.2M inmates
Every year in the US 60,000 children are sexually abused; ~220,000 adults sexually abused or raped; ~19,000 military members experience unwanted sexual contact. [1]
US prisons only seem over crowded until you see the number of violent crimes in the country, it basically works out to a sexual assault/rape every 90 seconds, it's pretty disturbing.
