1.I think that southern racist politicians used the term “law and order” to defend segregation as a way to blame the civil rights movements going on deeming them as “violent”. They also used this to gain a hold with poor southern white people and other people who supported segregation to gain votes. They used this term specifically because they could legally install a racial hierarchy without breaking any laws.
2.I think that the southern strategy is still strongly influencing politics to this day. The goal of the southern strategy is to get the vote of working class southern white people and try to divide people based on race promising to cater to white conservative voters in the south. One example is the former president Donald Trump during the BLM protests where he called protestors thugs and even before that where he has said some very controversial statements on different groups of minorities. This shows how he can get away with using rhetoric like that because a majority of people that are republican share these same views so they will agree with these statements no matter how prejudiced it may be.
