"I have been waiting to go nuts on the Patriot Act for such a long time ... not politically, but I love this legislation," Jim Cramer told viewers of his "Mad Money" TV show Wednesday.

"I love spying. I love surveillance," Cramer said. And that's because he believes there's money to be made now that many provisions of the Patriot Act have been made permanent.

Now that we can record, wiretap and video tape everyone in America, how will we keep track of all that information? NICE Systems ( NICE) is how, says Cramer. The company specializes in exactly what we need in these times, he said, because it takes loose, unstructured data and analyzes the information until it turns into something useful.

If the government is tapping your phone to determine if you're planning to blow yourself up in a public place, Cramer said, NICE will pore through your phone calls and pull up the relevant data if there are any.

These are the spy bureaucrats, he said, and they also make state-of-the-art command and control centers.

Plus, the company is the only voice-over-Internet-protocol play Cramer can get behind because it's one of the very rare plays in the VoIP sector that is actually profitable. And since Internet phones are cheaper than land lines, he wouldn't be surprised if companies switched over and NICE profited from the move.

He also said that the company is the leader in recording voice-over-Internet conversations. Every time you hear "This call may be monitored to ensure quality," he said that's NICE at work.

Cramer told a caller that Viisage ( VISG), which makes facial and fingerprint recognition systems, is another great play on the Patriot Act.

Bidding on Sotheby's

The Japanese have declared that deflation is dead, and the way to make some mad money is to buy Sotheby's ( BID).

When Japan sees inflation, you need to buy the best auction house in the world, because during the country's unprecedented period of inflation back in the 1980s and early 1990s, Japan was "the epicenter of the art market," Cramer said.

He could not say why this was the case, but reminded viewers that the last time around a Japanese dry cleaner bought a Warhol for $7 million.

Sotheby's is also positioned right where it was before the dot-com boom, he said, before the stock jumped because people thought it would dominate the online auction boom.

The bubble ended and Sotheby's stock came crashing back down, and Cramer believes that it's ready to run again thanks to Japan and because the global art market is on fire.

And a lot of that growth was propelled by art-buying in Brazil, Russia, India and China, economies that will continue to post great growth.

The company just reported a quarter that was "frankly fantastic," he said, and that it had its best year in 15 years.

Some are worried that the art cycle is peaking, but Cramer said that Sotheby's is right for an investment and for a trade.

It's great for a trade because there is an annual catalyst in May, when all the really big contemporary and impressionist art sales happen.

These sales will be covered in the media everywhere and the stock is likely to pop as a result, he said.

Cramer recommended taking a double-down position before the big sale in May, sell some into the spike and keep the rest as an investment.

The Writing's in the DNA

The mantra "buy low and sell high" is a bit misleading, Cramer said, because it's often taken to mean that investors should buy only when stocks are down and only sell when they're up.

You can't always get in on a stock at the bottom and sometimes you have to cut your losses and sell because there's no way the stock you own will go higher, he said.

"But if you see weakness in a stock you want ... then you absolutely must buy into weakness and wait to sell into some strength," he said, and that's why he believes now is the time to buy Solexa ( SLXA).

Cramer has been waiting for the stock to come down from its high around $12, and now that it's at $8 and change, he said to look into the gene-sequencing company. Solexa has a new machine to roll out that reads DNA.

The machine also has a range of uses outside of DNA reading, Cramer said, and he believes that it is faster, cheaper and more productive than other options.

He said that there's no comparison between Solexa and Human Genome Sciences ( HGSI), a company that he called a "serial disappointer." Human Genome starts with already decoded DNA and then uses that information to develop medicines, while Solexa reads the DNA.

Viewer Questions

A viewer said that as a firefighter, he wanted to know if Cramer would buy companies that meet the needs of police departments, fire departments and hospitals, including Federal Signal ( FSS) and Tyco ( TYC).

Cramer said that the viewer right to look for investment ideas in the world around him but that the best play on emergency services is Oshkosh Truck ( OSK), the "emergency vehicle play."

Another viewer wanted to know why Cramer recommended Broadwing ( BWNG), but then recommended selling it two weeks later because "the company dumped 7 million shares."

"Don't the underlying fundamentals still make it a good investment?" she asked in her email.

Cramer said that he never recommended selling the stock. "I said shame on management for taking advantage of what we are doing" when we buy the stock.

The price went up and management then sold a big chunk in a private placement, under the market, Cramer said.

"I don't like that because I'm trying to protect you from that kind of stuff," he said. That said, he pointed out that with Broadwing trading near its 52-week high, money was made.
