bbm sbm I've read similar stmts about minority parents having "The Talk" w their children about how to behave at traffic stops or during other contact w LEOs. I have no doubt many minority families have such discussions.
In talking w neighbors, co-workers, friends over the years, many white parents have said they had have multiple discussions along the same line: be cooperative, say yes officer, no officer, accept any warning or ticket from LEO, must wait to dispute in court, etc. Kids, esp teens, out & about, driving or otherwise not in the immediate watchful eyes of parents may very well be tempted to be sass back/be a smart aleck/show off for friends, etc, in the presence of LEOs.
BTW, have heard women admonish their husbands about tendency to be confrontational w LEOs.:thinking: Maybe goes in the opposite direction for some couples. IDK. JM2cts.
