The reason why no–one really knows why he was killed is that there is no agreement about who was behind the murder, who pulled the trigger or triggers, or even how many triggers were pulled.

Criticizing the government
Women, for example, during the WWII did a lot of manufacturing jobs in the US because there was a shortage of men because they were fightng in the war so to keep production going women had to take up the slack in other words it was an opportunity for them. Also, women fought for and gained the right to vote which gave them say in who the government was and also began to run for office in some cases. Women also began to study subjects which had been men's domain before-like engineering, geology etc.
