Answer:
Option 3
Step-by-step explanation:
Trump supporters stormed the capital on January 6th, 2021, due to disagreement about the legitamacy of Biden winning the presidency fair and square. (the trump supporters believed that there were faked ballots).
This could have been prevented by:
1. Trump should have refrained from suggesting violent acts on twitter
2. The police should have blocked people from entering instead of "seeing them in" and taking selfies with the protesters while at it.
If a protest at all, it should have been peaceful, violence is NEVER okay, especially when the lives of innocent people risked.
