Can I get indecent exposure charged expunged in Pennsylvania?

Pennsylvania in the last few years has passed new legislation (called Act 5) which does permit the sealing of certain minor, non-violent criminal charges.  In general you have to be crime free for 7-10 years from the time your penalty was served.  There are, however, exceptions for crimes which require reporting under the various iterations of Megan's Law.  Initially it appears the indecent exposure may exclude you from relief.  It would be worth your time to consult with an attorney to see whether you are eligible.  If you are not eligible the only way to have these charges removed from your record is to apply for a pardon from the governor.  This is not a quick process and often times an attorneys touch can help with the application process.  Good luck.
