Answer:
No, presidents should not have the power to take away the civil liberties of Americans. The Constitution specifically states that citizens have certain rights and protections, and it is not up to the president to override those rights. Furthermore, the president is not a judge and should not be making decisions about whether someone is guilty or innocent.
In times of war, the president may have more power to take away certain civil liberties in order to protect the nation, but these decisions should be made with extreme caution and with the understanding that civil liberties are essential to a functioning democracy. Such decisions should also be made with the understanding that the war must be necessary and justified, and that the president must be held accountable for any such decisions.
