Deductions & credits

The sites I refer to ....when i said "sights" were the IRS website and the IRS pdf "law book" whatever their elongated form of rules are per item.... 

I just want to get clarity if they wanted no felons to file for this then why not say IF U GOT A FELONY CONVICTION FOR DRUG POS. YOU CANNOT ...but it does not ..... it dances around the idea of such and says within....
