Which of the following was key evidence against sacco

The key evidence against Sacco was that one of the bullets was said to have been fired from his gun.

Explanation:

Nicola Sacco was an Italian anarchist who, together with Bartolomeo Vanzetti, was arrested, tried, and electrocuted in Massachusetts on 1927, under the charge of stealing $ 15,766.51 from a shoe factory, the assassination of his accountant named Frederick Parmenter and a security guard named Alessandro Berardelli, despite much doubt of his guilt

The events took place in April 1920, with three berths. Both had alibi, but were the only accused of the crime. With Sacco and Vanzetti the police found weapons and ammunition; however, the ballistics test was confusing, without reaching consensus as to whether the bullets that killed the accountant and his security had departed from the weapon they found with Italian anarchists. The witnesses were also confused and contradictory, which made it even more difficult to find the truth.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.

answer: a parliamentary system is a system of democratic governance of a state where the executive derives its democratic legitimacy from its ability to command the confidence of the legislature, typically a parliament, and is also held accountable to that parliament. in a parliamentary system, the head of state is usually a person distinct from the head of government. this is in contrast to a presidential system, where the head of state often is also the head of government and, most importantly, the executive does not derive its democratic legitimacy from the legislature.

countries with parliamentary democracies may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament (such as the united kingdom, denmark, sweden, and japan), or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature (such as ireland, germany, india, and italy). in a few parliamentary republics, such as botswana, south africa, and suriname, among some others, the head of government is also head of state, but is elected by and is answerable to parliament. in bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

parliamentarianism is the dominant form of government in europe, with 32 of its 50 sovereign states being parliamentarian. it is also common in the caribbean, being the form of government of 10 of its 13 island states, and in oceania. elsewhere in the world, parliamentary countries are less common, but they are distributed through all continents, most often in former colonies of the british empire that subscribe to a particular brand of parliamentarianism known as the westminster system.
