Homeland Defense and Security Investment Conference Addresses Gaps in Homeland Security and Educates Attendees How Small Company Technologies Can Play Key Roles in Long-Term Solutions


POINT ROBERTS, Wash. and SEVERNA PARK, Md., March 31, 2004 (PRIMEZONE) -- www.homelanddefensestocks.com and www.DomesticPreparedness.com are pleased to announce that the March 30th Investment Opportunities in Homeland Defense and Security Conference will be available in audio on both sites next week for investors and industry to review.

The presenting twelve public companies and five industry speakers educated investors, media and industry analysts at the conference on the long-term prospects and potential of the homeland security industry.


 Key points addressed by the speakers include the following
 highlights:

 - There is no silver bullet solution to solve homeland security
   concerns; rather fused or integrated technology solutions are
   required.

 - It is anticipated that 90% of new technologies will come from
   small flourishing companies.

 - Larger defense companies are creating new homeland security
   divisions to participate in the sector.

 - It is anticipated that mergers and acquisitions will increase.

 - Jack Mallon's Security Index out-performed all major market
   indexes in 2003, with TASER International (TASR) leading the pack.
   The Index was up 56% over the year.

 - The homeland security industry is the fastest-growing industry
   in our lifetime.

 - Bioterrorism detection and vaccines are primary concerns to be
   addressed moving forward.

"The speakers and presenting companies left all of us with a wealth of new information to digest. Once the archived audio files are available next week, I would recommend investors listen to the conference speakers for an in-depth overview of the industry opportunities and obstacles. HomelandDefenseStocks.com will follow the companies over the course of the coming year and monitor their technology deployment strategy and how it impacts their revenue stream and stock performance," said Dawn Van Zant, President of ECON Investor Relations, Inc.
