The Elder Scrolls IV: Oblivion Tips

I killed someone & I'm not in trouble! ;)
now to do this you need: invisibility spell, & the mask of the grey fox you get after mastering the thief's guild (sorry, i forgot the name).

before you kill, steal, or do some other illegal bull, equip the mask, then do the illegal things you want to do, then when you want to be a good person again, just activate the invisibility spell, then take off the cowl, finally walk up to the guard, still invisible, & press 'X' wile shielding. The guard will hate you, but you won't get into any legal trouble.
