You should tell them the truth. You never know which records/databases they will check: they may check the records of the local courts, police departments where you lived in the last 5 years.
Answer "Yes" but attach the copy of the court decision to dismiss the charges. If you get cought for lying you will never get the clearence.

for 5C dolzen skazat kak est ili popadesh v black list goverment contractor.,vozmozno felony
pri obstoiatelstvah vipolnenia kontrakta.

You must list everything, they will do state-wide police/courthouse checks anyway so they will find out but if you don't list it-you'll be falsifying federal documents, which is a felony..I wouldn't recommend it. Plus, after you don't list it and they find out, they have to open a special investigation just for you....and that won't be fun either because you'll have to face a confrontational interview with not such a nice agent, under oath, so vsemi istekayushimi......might as well tell them the truth, they'll find it out within 2 days anyway.
