<p>Federal agencies, in general, do not have sworn LE officers doing PR/PAO duties. That’s because LE is, in many cases, just one part of the work done by a broader agency. (Think Customs and Border Protection, National Park Service, Bureau of Land Management, Bureau of Indian Affairs, etc.)</p>
<p>Also, the GS classifications for LE and PAO work are totally different. LE officers have a separate payscale and retirement system (that are more generous than the normal GS grades) and therefore agencies would prefer not to pay someone LE money who isn’t doing LE work. There are exceptions to this - like the Border Patrol.</p>
