Generally no....... They DO make wide band Communications Receivers but the cost is expensive..... Only the more serious hardcore radio listeners purchase these.....
Here are a couple of models......

The Bearcat BCT8 is a decent VHF / UHF radio, but it does not have the capability of listening to most of the HF band..... It does pick up the 25 to 30 MHZ part of the HF spectrum but theres not much to listen to there.... Some CB radio and a few ham operators and that's it.....

I do suggest this...... If you want to listen to shortwave radio, and VHF / UHF (police) frequency's then purchase 2 radios...... You can save a lot of money doing this....
Here is a nice semiprofessional HF (shortwave) radio.....

If this is a bit rich for your budget then surely look at this model......
