Rodney King's daughter knows Tyre Nichols' family is going to be in a world of hurt for a long time once the world sees the extent of their loved one's fatal beating ... and she's offering some advice before the body cam footage is released.
Lora King tells TMZ the pain her family went through after her father was brutally beaten by cops was indescribable -- adding the whole thing continues playing on a loop in your head after seeing the video, as Tyre's family has.
While she's trying to offer them some guidance, she also notes nothing can really prepare them for just how heartbroken they'll be while going through the legal process, and watching the public's reaction.
Lora was only 7 years old when the police brutality against her dad sparked nationwide outrage, which eventually erupted with massive riots when the involved LAPD officers were acquitted.
King died in 2012 of an accidental drowning in his pool.
Attorney Ben Crump -- who is repping Tyre's family and saw the body cam video of the arrest -- called the clip "appalling" and "heinous" and likened it to the beating of Rodney King.
