Drawing references to increased crime rates in major U.S. cities, Republican presidential nominee Donald Trump proposed during the first presidential debate Monday that police should be allowed to stop-and-frisk anyone they consider suspicious.

According to a Rasmussen poll, 41 percent of likely U.S. voters favor stop-and-frisk law while Clinton supporters are of the view that minorities would be "unfairly targeted" under such laws.

The results:

Favor: 41 percent.

Oppose: 47 percent.

Undecided: 12 percent.

However, voters who are in support of such laws showed concern that rights may be violated.

There has been a rise from 36 percent among those who favored the law three years ago. In the previous survey, 50 percent said they opposed the law.

While 39 percent say stop-and-frisk laws decrease crime, the same number believe they have no impact. The findings, which are similar to 2013 polls, showed only 13 percent think such laws increase crime.

One of the reasons which makes stop-and-frisk law unacceptable is voters feel rights of some Americans may get violated. While 65 percent of voters are somewhat concerned the law might violate rights, 39 percent are very concerned.

Thirty-three percent of respondents don't think rights will be violated and 13 percent are not concerned that some Americans' rights could be violated. These findings, too, are similar to past surveys, according to the report.

The survey, which had 1,000 likely voters, was conducted on September 22 and 25. The margin of sampling error is +/- 3 percentage points.
