Final answer:
Under federal laws, individuals who misuse confidential information, such as an IRS employee browsing tax returns, or violate intellectual property rights by stealing passwords for software downloads, can be found guilty. This also applies to individuals who steal sensitive government property with the intent to sell, such as DEA agent lists.
Step-by-step explanation:
When deciding whether property was deprived under federal laws, several scenarios might warrant a guilty verdict. These include actions that violate intellectual property rights or involve the improper use of confidential information. Utilizing the reference information provided, one can determine which individuals would likely be found guilty.
An IRS employee who browsed tax returns for personal use could certainly be found guilty as this action is a violation of privacy and misuse of confidential and protected information. A defendant who stole a password to download proprietary software would also be found guilty because intellectual property laws protect such software, as demonstrated in the MGM Studios v. Grokster case where companies enabling copyright infringement were held liable. It is similar to the illegal downloading of music or movies, which affects the creator's economic rights.
Additionally, a defendant who took a list of DEA undercover agents with the intent to sell is guilty because this represents a theft of government property intended to protect agents' safety and undermine law enforcement activities. Lastly, depending on context, a defendant who used a classified computer to store ballroom dancing material might not be found guilty under federal laws if no property was deprived or laws were broken, but could face consequences for misuse of government resources.
The responses suggest the following options could be right: (b) defendant who stole a password to download proprietary software, and (c) defendant who took a list of DEA undercover agents with intent to sell. The IRS employee could also potentially be found guilty depending on the specific circumstances surrounding the browsing of tax returns for personal use. I would need more context about the classified computer and ballroom dancing materials to make a determination, hence it is not listed as a correct option in the final answer.
